help is needed - failed to start drivers while installing PowerVR drivers

Hi,

I started installing OMAP35xx_GFX_SDK_Beagle, which I got from TI, on
my beagleboard following the INSTALL instructions.
I booted the board and tried to start the drivers but it failed.

Bellow is the output of the command:

root@beagleboard:~# /etc/init.d/rc.pvr start
pvrsrvkm: disagrees about version of symbol struct_module
insmod: error inserting 'pvrsrvkm.ko': -1 Invalid module format
mknod: missing operand after `0'
Try `mknod --help' for more information.
chmod: cannot access `/dev/pvrsrvkm': No such file or directory
omaplfb: disagrees about version of symbol struct_module
insmod: error inserting 'omaplfb.ko': -1 Invalid module format
root@beagleboard:~#

/* bellow is some information about the kernel version:
root@beagleboard:~# uname -rsnm
Linux beagleboard 2.6.28-omap1 armv7l

Can someone suggest how to solve it, it will be grateful.
