Try a newer kernel. Or, alternatively, you could replace tinybios with
coreboot (http://coreboot.org) as I do :)

This is 2.6.26.5 on top of coreboot, alix 2c3:

eth0: VIA Rhine III (Management Adapter) at 0xfebfa000, 00:0d:b9:13:4a:dc,
IRQ 10.
eth0: MII PHY found at address 1, status 0x7849 advertising 05e1 Link 0000.
PCI: Guessed IRQ 11 for device 0000:00:0a.0
eth1: VIA Rhine III (Management Adapter) at 0xfebfb000, 00:0d:b9:13:4a:dd,
IRQ 11.
eth1: MII PHY found at address 1, status 0x7849 advertising 05e1 Link 0000.
PCI: Guessed IRQ 11 for device 0000:00:0b.0
PCI: Sharing IRQ 11 with 0000:00:0f.4
PCI: Sharing IRQ 11 with 0000:00:0f.5
eth2: VIA Rhine III (Management Adapter) at 0xfebfc000, 00:0d:b9:13:4a:de,
IRQ 11.
eth2: MII PHY found at address 1, status 0x7849 advertising 05e1 Link 0000.

Thanks,
