14 One of the things you might consider doing is jumping into the busybox
15 shell and poking around /dev for the names of the devices you have. (I'm
16 assuming you boot with grub - that's what those messages look like to
17 me.) You might be able to "insmod" all your modules from there, too, and
18 see if you get the devices installed.

20 Roc, in one of your posts, you listed your grub.conf line and, according
21 to the gmane entry, anyway, it looks like it's split across two lines.
22 Could it be that simple? Is your grub.conf entry for the kernel command
23 on just one line? (Genkernel added the entry so I'm obviously grabbing
24 at straws here....)
