Yeah it was crashing in static int force_8bit_access_check_and_set
in linux/drivers/pcmcia/cistpl.c, apparently while doing an
        GPSR(GPIO54_nPCE_2) = GPSR(GPIO54_nPCE_2);
Patched that (patch-pxa-gpsr, attached), and now the boot seems
to be hanging somewhere in userland...

 Yeah it has an fn key that is used to generate most special characters...
But even shift didn't work on the 2.4 kernel's console (and as I said
fn apparently got lost too), and with the poky rxvt it seemed like
anything that uses fn caused an error (cursor flashes quickly) instead
of sending the corresponding character.
