I'll give this a try I do get a line in dmesg which reads:

PCI-DMA: Disabling IOMMU.

Re: skge error; hangs w/ hardware memory hole

OK, here are the results with iommu=force. All of these are copied down
by hand, so please forgive any transcription errors:

2.6.12[1]: Last line displayed on screen is "ata1: dev 0 ATA max
UDMA/133 390721968 sectors, lba48". Then it sits there. Scrolling with
shift-pgup/pgdown works. Control-Alt-Del reboots the machine. According
to /var/log/dmesg, the next line --- which never appears --- should be
"ata1: dev 0 configured for UDMA/133"

2.6.17-1: The kernel panics with a null pointer dereference on loading
uhci_hcd. The addresses given are usb_kick_khud+7, usb_hc_died+106,
pcibios_set_master+30, etc. After the panic, it sits there (just like
2.6.12)

2.6.17-mm6: The last line displayed is "SATA link up 1.5 Gbps SStatus
113 Scontrol 300". It completely hangs: neither scrolling nor
control-alt-del work.


Honestly, should I chuck this board through the window of my nearest
ASUS and/or VIA office, and buy an NForce board?

Didn't work :-(

Excepts from the log:

Bootdata ok (command line is BOOT_IMAGE=2.6.17-1-smp ro root=902
iommu=soft swiotlb=force single)
...
skge eth0: enabling interface
skge :00:0a.0: PCI error cmd=0x117 status=0x22b0
skge unable to clear error (so ignoring them)
skge eth0: Link is up at 1000 Mbps, full duplex, flow control tx and rx

And then the NIC didn't work. Attaching full dmesg.
