Subjectagp driver (?) triggering an oops

I often get an oops under 2.2.14, when I start X Window with glx
(utah-glx). It seems reloading the agp driver (from utah-glx) triggers it.

Here is one of those oppses run through by ksymoops (in fact, it's always
the same):

ksymoops 2.3.3 on i686 2.2.14. Options used
-V (specified)
-k /proc/ksyms (specified)
-l /proc/modules (default)
-O (specified)
-M (specified)

Unable to handle kernel paging request at virtual address ce834b24
current->tss.cr3 = 0af64000, %cr3 = 0af64000

I have seached the utah-glx's mailing list archives and I seem to be the
only one to experience this problem. Any ideas what can be wrong on my end
? The version of modutils is 2.3.9.

Under 2.3.x, no such an oops. Instead, several messages ('memory
: cbd006c0') found in kern.log.
