[pwc] Invalid module format

["buzz lightyear" <>]

Hi

When I had fc3 installed, my quickcam 4000 pro worked fine with 
gnomemeeting.
When I installed fc4 all I got was a grey screen.

I've just downloaded pwc-10.0.7a and compiled ... warnings:

I then did a find /lib/modules/`uname -r`/ -name "pwc*.ko*"
and removed the pwc.ko

I then did a make install and got:
make -C /lib/modules/2.6.12-1.1390_FC4smp/source

install -m 644 -c pwc.ko 
/lib/modules/2.6.12-1.1390_FC4smp/kernel/drivers/usb/media
/sbin/depmod -a

I then did a 'rmmod pwc' follwed by a 'modprobe pwc' and got the following 
error:
FATAL: Error inserting pwc 
(/lib/modules/2.6.12-1.1390_FC4smp/kernel/drivers/usb/media/pwc.ko): Invalid 
module format

I'd be very grateful for any input as to what I did wrong

Thanks in advance

Nick
