Did Barton based CPUs have an integrated memory controller?
no

interesting. back in 2008-2009 Biostar made PCIe ddr2 socket 478 motherboards, wich ran/run quite well. i guess since Barton didn't have an IMC either it is technically possible a similar board could have been made.

P4M890 most typically was the chipset of choice from VIA, it was ok for single core cpus only. The bad part was that the pci-e slot only worked in 4x mode and the memory controller was horrible to the extent that in some situations it was faster to use DDR1.

I suppose it would have been technically possible, but keep in mind the only reason there were DDR2 S478 boards was because the chipsets used with the S775 chips were generally backwards compatible with the older CPUs. Manufacturers could pretty much just take one of their low-end S775 board designs, run it back through the trace routing process with a S478 template in place of the S775 template, and spit out S478 boards with minimal R&D cost.
There was no such backwards compatibility for the Athlon chipsets though, so a DDR2 Athlon XP board would have required a chip-maker to be crazy/stupid enough to design a new chipset for a long-dead platform, and also an equally crazy/stupid board manufacturer to design a new line of motherboards around said chipset.
I've been looking at late low-end P4 server boards recently, and was wishing I could find an mPGA478 board with the i7221 chipset (similar to the 915 I believe). Not because of DDR2, but as it happens the i7221 is a DDR2 chipset. Seems nobody ever did it though, all of them are LGA775.
You've got me curious about Biostar. I see a 945 mPGA478 on their site, looks like they made some interesting boards.
I have used 2 of their skt 478 ddr2 boards they seem to work alright, i got one to play crysis on low. they don't OC that great and the VRMs run crazy stupid hot.
Also you can buy an lga775 to 478 converter
