Could just be my hardware, but I was not able to get a 486 PCI motherboard to boot from a PCI IDE card, BIOS or no BIOS.

It's your hardware... I was able to successfully use a relatively late Promise PCI card and it worked fine. The motherboard was a Shuttle HOT-433.

Did it have onboard bios?

p.s. now that I think about it, I never tried the pci cards in the m919 board.

IDE controllers >= 1994 are the better ones.

A 1994 Prime2C controller can work at 18.75Mhz ISA bus clock.

Winbond, Western Digital are good too.

I've got an AOpen AP43 booting off a PCI Promise Ultra66 myself, no issues.

I remember back in the VLB days there were some really wacky combo SuperVGA+IDE/Floppy/IO cards made like the FIC COMBO-542VP and Paradise Ports O' Call.

With the VLB card market priced as it is... maybe a buy once-cry once approach is sensible.
