vmware recent kernel support?
 

anyone know how to get vmware wk4.0 working under 2.6x kernel?

You need to get the patch: http://ftp.cvut.cz/vmware/
Installation instructions: http://kerneltrap.org/node/view/1804

I've heard that the new 4.5 version has support for 2.6 but I haven't used or investigated it yet.

Yes I tested vmware 4.5 it works well on kernel 2.6.4
..but I currently have some problems compiling the module on 2.6.5
It won't build modules correctly; have the same problem with the nvidia kernel interface.
