Very cool!

I uploaded a newer patch that fixes the memory size problem and the slow
timer. This version also knows how to output the kernel command line
prompt to the vga. The boot graphics driver uses whatever is configured
in the firmware for the x-server. You need to disable CONFIG_VGA_CONSOLE
for the built-in fb driver to work. As you said, this driver does not init
the VGA registers, so it will only run at the resolution set by the
firmware.

Can you also post what you added to the fb driver? Is that the init code
from cyberfb.c?

Don't know about alsa. The kernel contains an OSS driver for the Chrystal
Semi CS4232, but the PReP code in arch/ppc/prep_setup.c is broken. The
broken code does nothing more than load the driver with the proper settings
for the machine, i.e. io, interrupt, dma - I think. You should be able to
enable modules for the kernel, compile cs4232 as module, and insmod with
proper command line options.

One weird thing with the nfs root fs -- the mount command does not show any
of the mounts, i.e. rootfs, /proc, /dev, etc. ???? The nfs root fs works
very nicely otherwise.
