Re: via 6420 pata/sata controller

[Jeff Garzik]

If I had to guess, I would try the attached patch.  The via82cxxx.c 
driver is a bit annoying in that, here we do not talk to the ISA bridge 
but to the PCI device 0x4149 itself.

If this doesn't work, I could probably whip together a quick PATA driver 
for libata that works on this hardware.
