with the above applied:

VP_IDE: VIA vt82c686b (rev 40) IDE UDMA100 controller on pci00:07.1
    ide0: BM-DMA at 0xd000-0xd007, BIOS settings: hda:DMA, hdb:pio
    ide1: BM-DMA at 0xd008-0xd00f, BIOS settings: hdc:DMA, hdd:DMA
hda: ST380021A, ATA DISK drive
hda: DMA disabled
blk: queue c02d28a0, I/O limit 4095Mb (mask 0xffffffff)
hda: DMA enabled
hdc: PLEXTOR CD-R PX-W2410A, ATAPI CD/DVD-ROM drive
hdd: CD-532E-B, ATAPI CD/DVD-ROM drive
hdc: DMA disabled
hdc: DMA enabled
hdd: DMA disabled
hdd: DMA enabled
...

message is printed after via_init_one() completes, but that's just
about all I've been able to find out. :(
