Hrm... can you try to edit
arch/ppc/platforms/pmac_cache.S, and spot that bit of code:

        /* disp-flush L1 */
        li      r4,0x4000
        mtctr   r4
        lis     r4,0xfff0
1:      lwz     r0,0(r4)
        addi    r4,r4,32
        bdnz    1b
        sync
        isync

And change the line

        lis     r4,0xfff0

to

        li      r4,0

and tell me if that helps...
