Subject: 2.6.21: longhaul freq-scaling broken

Hi,

the new longhaul driver of 2.6.21 is broken on my Via Eden board.
Frequencies can no longer be switched by whatever governor.

# cat /proc/cpuinfo
processor       : 0
vendor_id       : CentaurHauls
cpu family      : 6
model           : 7

bogomips        : 1200.75
clflush size    : 32

I ported the longhaul driver from 2.6.20.7 to 2.6.21, it works fine.

Yeah, I know there are only a few patches between both, but I would like
to reduce the test cycles to a minimum. Any suggestion where to look
first is welcome therefore, ready-to-apply patches even more...

Thanks,
Jan
