o.k. finally finished with the bisect:

reverting this gets things going on 2.6.33-rc5

    x86: Fix fixmap ordering

    The merge of the 32- and 64-bit fixmap headers made a latent
    bug on x86-64 a real one: with the right config settings
    it is possible for FIX_OHCI1394_BASE to overlap the FIX_BTMAP_*
    range.

The only thing I can think of at this point
is maybe the CFLAGS I used to build this system.
(as for the x86_32 working and x86_64 failing not sure);

I'm curious to see if anybody else is hitting this?
