Okay, I overcome the first problem by installing gentoo from an existing hdd gentoo installation. I borrowed my friends' hdd for it.

Err. None of a, b, c could boot. I feel a bit wired, a) is cdrom, b) is ide@3/disk but the hdd on IDE card should be ide5 (count from 1) or ide4 (count from 0)

Is it possible at all to put the boot loader onto floppy like some people did for their x86 box? I see the kernel is pretty big (3.6MB), but squezze down it seems could reach 1.44MB.
