That's indeed probable, but if enough people report the same problems, they 
might still end up looking into it.

That's quite a bold claim considering that the VT8251 includes many different 
functions (PATA, SATA, USB, SMBus...) and can be configured differently on 
different motherboards. Maybe most functions are supposedly supported as of 
2.6.20, but it doesn't mean everything works for everyone, as you are 
experiencing yourself.

If it's not a VIA IRQ problem, then there's nothing more I can do, sorry. 
Someone else will have to look into the problem.

Out of curiosity, with my patch applied, did you see any "VIA VLink IRQ fixup" 
messages on the console?
