kernel-2.6.11.8 and vmware-4.5.1 question?

[Ishwar Rattan <ishwar@pali.cps.cmich.edu>]

I am running kernel-2.6.11.8 and trying to install
vmware-4.5.1 (for Linux host). An attempt to insmod

 # insmod ./vmnet.ko

results in

 insmod: error inserting './vmnet.ko': -1 Unknown symbol in module

Does vmware-4.5.1 works with 2.6 kernels?
