that fixed the build but now we've got a boot crash with this config:

 time.c: Detected 2010.304 MHz processor.
 spurious 8259A interrupt: IRQ7.
 BUG: unable to handle kernel NULL pointer dereference at  0000000000000000
 IP: [<0000000000000000>]
 PGD 0
 Thread overran stack, or stack corrupted
 Oops: 0010 [1] SMP
 CPU 0

with:

  http://redhat.com/~mingo/misc/config-Thu_Jun_26_12_46_46_CEST_2008.bad
