As far as I know, grub doesn't use the Linux /dev/ nodes to access
disks. The syntax for both IDE and SATA drives should be the same for
your menu.lst, so something along the lines of groot=(hd0,0). Since
you are using the secondary drive (in Linux, /dev/sdb) I guess it
would probably be groot=(hd1,0). You'd still want kopt=root=/dev/sdb1
as it is though, since that parameter is intended for the kernel and
not the bootloader.
Well groot=(hd2,0) works - that is, when trying to boot I now get a
Filesystem type is ext2fs, partition type 0x83

Is your /boot on a separate partition?
Please post more information on your partition layout. At the very least
mention the partition of your /boot and the total number of disks in
your system. You mentioned having two SATA drives, but do you also have
any IDE drives?
The 'groot=<dev>' line in menu.lst should be commented out with a single
'#'. update-grub uses this line to figure out the partition where your
/boot is located. If your /boot is on a dedicated partition, then the
kernel would be found in the root of that filesystem. So the kernel line
kernel /vmlinuz-2.6.26-1-amd64 root=/dev/sdb1
If you are able to get to a grub prompt while booting, you can manually
specify the kernel and vmlinuz and use <tab> for autocomplete.
At the grub prompt, press 'c' to get to the console.
type root (hd<tab>
that should list all the drives. Select the appropriate number, and
press <tab> to list the paritions. Select the partition that makes most
type 'kernel /<tab>' and use tabcompletion to point grub to the correct
kernel and initrd.
Once you have all the needed info, you can modify menu.lst appropriately.
If you can't explain it simply, you don't understand it well enough.
