It appears that GRUB is doing it's job, but the kernel does not have the 
appropriate HW drivers for VMware's emulation.  If you have another 
VMware system that works, boot to that and run both lspci and lsmod to 
see what that system is being loaded.  Then rebuild your kernel ensuring 
the proper drivers are built into the kernel.
