Hmm, with 512 MB seabios should have paniced here with:
PCI: out of address space
> PCI: map device bus 0, bfd 0x28
> bar 0, addr febe0000, size 10000 [mem]

Somehow seabios didn't recognise the bar correctly it seems (both 512
and 256 MB cases look the same). For the 256 MB case seabios should
have mapped the bar @ 0xe0000000.
cheers,
Gerd
