Radeon 9200 Attempt to free NULL pointer

[Warren Togami]

XFree86-4.3.0-40
kernel-2.4.22-1.2097.nptl (athlon)
Athlon64 + MSI Neo
Fedora Core 0.95 (32bit)

X seems to work fine with this video card, with full 3D DRI acceleration 
using the fully open source drivers included in Mike's excellent 
packages.  However every time I restart X these messages appear in dmesg:

[drm:radeon_ioremapfree:mappings] *ERROR* Excess frees: 3 frees, 2 allocs
[drm:radeon_ioremapfree:mappings] *ERROR* Attempt to free NULL pointer
[drm:radeon_ioremapfree:mappings] *ERROR* Excess frees: 4 frees, 2 allocs

Should I worry about this?  Bugzilla?

Thanks,
