Yes, that's on my list. Unfortunately this has so far only been seen on my workstation, and I have to get a bit of work done before I can pursue this. At least I can get some candidates built in the background.
I have tried a few things quickly with 22-rc2, and the short summary is:
* noapic makes no difference (don't recall why I had UP APIC enabled)
* disabling DMA w/hdparm stops the corruption (all normal operation and previous testing has been with DMA enabled)
* mounting w/ -o sync makes no difference except to slow things down
