I meant the patch to sort the exception tables, which fixes the
only problem I know that unit-at-a-time triggered on i386

Looks like the sort extable patch was missing. Are you 100% 
sure you booted the right kernel? 

2.6.2-rc1 has Paul Mackerras' generalized sort extable patch already.

I just booted an 2.6.2-rc1-mm3 kernel compiled with an -funit-at-a-time capable
gcc 3 and it worked just fine.
