linuxwacom kernel module

[Michael Favia]

For some reason the linuxwacom kernel module has failed to load in 
recent kernels.

[michaelfavia at lithium ~]$ /sbin/modprobe -v wacom
insmod /lib/modules/2.6.15-1.1853_FC5/kernel/drivers/usb/input/wacom.ko
FATAL: Error inserting wacom 
(/lib/modules/2.6.15-1.1853_FC5/kernel/drivers/usb/input/wacom.ko): 
Operation not permitted

/var/log/messages and /var/log/dmesg hold no clues. Any direction or 
file a bug? -mf
