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 0000:00:0a.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
