I can't say much, but we need and use the 3-D graphics.

We could just run Angel, U-Boot or Redboot but we would like LinuxBIOS
since there are PC type peripherals on-board, PCI bridges, southbridges,
audio accelerators etc (theswe are not weenie PDA boards). We may have
8-16 cpu's on PCI-X 64b/133. Areas where LinuxBIOS beats the pants off
the other bootloaders.
