Hi,
You shouldn't need scsi, which is used by ata module to access pci
bus, but openfirmware would export the boot disk for you.
Use these command:
set debug=disk
ls
This should print some debug information in grub console.
I try to do my best to clean up as much as possible info collected:

rem: `/vdevice/v-s...@30000016/d...@8100000000000000,1' this is well the string
put in nvram
(I try also to rm ',1' at the end but that doesn't help?)
That said, on my ibm p5 (I haven't access to any other system booting with
different ofs), I have to install grub on a
dedicated fs (as far as I understand, I can choose between hfs and fat, here I
select fat) as follow:
(p5_sid)r...@p5tst001:~# df
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/sdb6 2015808 1986772 29036 99% /
/dev/sdb3 247919 161597 86322 66% /boot
/dev/sdb1 23337 21302 2035 92% /boot/grub
[snip]
I copied my vmlinux and it's related initrd files in /boot/grub and use a
simplified grub.cfg:
set timeout=5
menuentry "Debian GNU/Linux, with Linux 2.6.30-2-powerpc64" {
linux /vmlinux-2.6.30-2-powerpc64
root=UUID=3c51c43e-63a7-4ff1-9b1c-cf98addcb7ed ro sysrq=1 insmod=sym53c8xx
insmod=ipr quiet
initrd /initrd.img-2.6.30-2-powerpc64
}
Ok, it always fall in rescue mode but shows me well a single line menu "Debian
GNU/Linux, with Linux 2.6.30-2-powerpc64" and
then my debian installation boot well ;<)
That's a bit like with grub legacy on my i386 where grub stand in the same fs
as boot but in a subdir
but that's just a tips and not what we want to do?
(afaik my reading told of max size of about 24Mb for /boot/grub fs, so it
wouldn't be able to contains a lot of kernel)
Thanks in advance for additional feedback,
J.
PS: those latest test was made with latest debian pkg src of
grub2_1.97+experimental.20091026-1.dsc without optimization (-O0)
