I have been trying different kernel configurations to overcome this
problem. I found that turning on APIC seem to work properly. However
turning on IO-APIC causes it to hang just after X is started, which
seems to be during the startup of gdm.
I do have a silly question to ask though. How do I compile the kernel
NOT to use pte in high memory?

This did not work as it causes vmware to seg fault with a kernel oops:
        Unable to handle kernel paging request at virtual address
         printing eip:
        *pde = 00001063
        *pte = 00000000
