Since i studied alot of pci legacy sound options, i can give a complete list of notes of the sound cards you mention. note some these legacy dma options for sound blaster sfx don't need a TSR program, but a chipset support at a bare minimum.
1.the Fortmedia SP-801 uses DDMA and a proprietary WSDMA mechanism (Write snooping the i8237 compatible DMAC, aka Write-snoop dma)
2.the Avance Logic als4000 uses DDMA, WBDMA "Write-back DMA" and a WSDMA mechanism (which i think the write snoop tech was plagiarized from ESS Tech from their legacy sound option because the datasheet registers are somewhat nearly identical.)
3.The ESS allegro line is similar to the ESS Solo-1 except it no longer has the ESFM and now has hardware software based FM emulation that sounds pretty bad, Like the Solo-1 chipset; It has access to SB-LINK, DDMA, 3 WBDMA modes and ESS Tech's proprietary write-snoop mechanism known as Transparent DMA "TDMA" which works well with pci chipsets that are well linked to the LPC bus. (Reason why early intel chipsets + all VIA chipsets work well with this tech)
4.Yamaha's 7x4 PCI audio chipset provides sound blaster support via SB-LINK, DDMA and a TSR that emulates DMA, though this sound card comes in different chip flavors which are similiar but function somewhat differently under Windows.
5.VIA's ice ensemble's "or ENVY 24 vt1712 audio chipset" when bridged with an ac97 codec from VIA, has DDMA support and software based FM emulation akin to early VIA chipsets with integrated sound blaster support. sadly this pci audio chipset can only work with aformention configuration when all the appropriate setup with audio chip is fully link to an external audio codec, which for some reason none of those stand alone sound cards don't provide them. (except those very rare SoC made from that taiwanese company that makes industrial computer boards had them integrated with an VIA ac97 audio codec chip)
6.Crystal CS481-CM from Cirrus Logic is an ac97 codec with no legacy features, so no sound blaster support with this one.
7.VIA's ice ensemble's Tremor VT1723 is the same with number 6 so no sound blaster support.
8.That sound card you listed last is the same as the first sound card you listed.
Out of all sound cards you listed, The allegro sound card is the most compatible out of technicality of being able to be used under real mode DOS instead of other card's relying on software emulation or rare and unreliable technologies like SB-LINK(Rare) or DDMA(has alot of issues on various chipset manufacturers that support this busmaster legacy function). Second most compatible is the Fortemedia audio chipsets but it has it's fare share of problems, which are listed in various other forum posts about this card.
Another card to add which also has great sound blaster compatibility without the need of an motherboard chipset dependent functionality is the aureal vortex cards which can be used in real mode DOS, be warned of it's FM implementation is something left to be desired. (sounds similar to the ESS Maestro and Allegro cards)
