PCI error on x86_64 2.6.13 kernel

[Jack Howarth]

    Using the latest 2.6.13 kernels in FC4 on a Sun dual opteron
workstation, I am seeing an error at boot time that doesn't happen
under older kernels.

Oct  3 11:21:48 diego kernel:   MEM window: d0200000-d02fffff
Oct  3 11:21:48 diego kernel:   PREFETCH window: disabled.
Oct  3 11:21:48 diego kernel: PCI: Failed to allocate mem resource #6:20000 at f0000000 for 0000:09:00.0

This appears to be a non-fatal error at first glance but is worrisome.
Has anyone else seen this problem and is there a fix of any sort?
