arcboot has a build dependency on gcc-2.95 for a reason, Easily fixable,
but not before the sarge release.

Did you check if your self built arcboot loads 32bit kernels at all
(e.g. on IP22), the one in the archive certainly does? 
I can't check myself, since i don't have an o2 nearby, but i was told
that booting viviens "old" IP32 2.5 kernels works. did you check if
anything in the link script changed since then? Could you explain the
problems that show up when trying to boot the kernel out of the vh,
maybe that's related?
