Vmware 4.5.1 & Knoppix 3.4 & kernel 2.6.6

Hello

I'm trying to install Vmware 4.5.1 in a Knoppix 3.4 withkernel 2.6.6 (boot knoppix26) installed in HD. I get an error of kernel sources, because i have 2.4 sources while i need 2.6.6. I have downloaded 2.6.6 from kernel.org, but these also don't work (it seems like knoppix 2.6.6 is a little bit modificated as i have read in knoppix-readme). Vmware installation says 2.6.6 kernel sources aren't the good ones for my kernel (but with #uname -a I got 2.6.6 ...)

Does somebody know what can i do? I'm getting crazy!!! :oops:
Thank you.
