Description of Problem:

drm modules from i386 kernel are trying to use cmpxchg function which is not
provided by i386 kernel. As a result: 


[root@leon root]# modprobe r128
/lib/modules/2.4.17-0.6/kernel/drivers/char/drm/r128.o: unresolved symbol cmpxchg
Version-Release number of selected component (if applicable):

I think it would be better to skip building drm modules for i386 kernel.

How Reproducible:

always

Steps to Reproduce:
1. install i386 kernel
2. try to insert drm module (r128, etc)


Actual Results:

unresolved symbol cmpxchg

Expected Results:

must be inserted

Additional Information:
	
2.4.17-0.6
