It's now atleast verified that it's only the ieee1394 path that causes
this problem.

What i did was that i got the drivers/ieee1394 folder from a 2.6.2
kernel and replaced the ieee1394 folder in the 2.6.7 kernel.

then patch the file ieee1394_types.h
since we dont have CLEAR_BITMAP function in 2.6.7.

so in here:
#define HPSB_TPOOL_INIT(_tp) \
do { \
        CLEAR_BITMAP((_tp)->pool, 64); \
        spin_lock_init(&(_tp)->lock); \
        (_tp)->next = 0; \
        (_tp)->allocations = 0; \
        sema_init(&(_tp)->count, 63); \
} while (0)

replace CLEAR_BITMAP with:
        memset((_tp)->pool, 0, BITS_TO_LONGS(64)*sizeof(unsigned long));

Also since there are a couple of more functions that are not accessible
from 2.6.7 any more i managed to compile this with the current settings:
  <M> IEEE 1394 (FireWire) support (EXPERIMENTAL)
  <M> OHCI-1394 support
  <M> SBP-2 support (Harddisks etc.)

Since cdev_unmap among other functions are removed from the 2.6.7 kernel
you cannot include anything like raw1394 and those... But atleast we got
something to go on from here and maybe create some patch...

Thoe, i'm not to good at kernel stuff so dont expect anything soon, or
even stable :D

Not shure how stable this is, but give it a try if you feel daring :D
