It seems that there is some conflicting information.  Patching the
kernel is necessary.  Without the patches you will get errors like:

FATAL: Error inserting gfs (/lib/modules/2.6.9/kernel/fs/gfs/gfs.ko):
Unknown symbol in module, or unknown parameter (see dmesg)

gfs: no version for "lm_mount" found: kernel tainted.

gfs: Unknown symbol panic_on_oops" errors in the logs.

The patches for the 2.6.9 kernel include the panic_on_oops symbol as
well as others.
