Hi Marc,
Still the system is hanging even after moving the drivers from the directory "mv /usr/X11R6/lib/modules/drivers/sun*_drv.o /temp".
On further debugging the code I identified that the system is hanging in function call xf86scanpci () within the while loop "while (idx < MAX_PCI_DEVICES && tag != PCI_NOT_FOUND)". I think this function scans for PCI devices present in the system by iterating through the while loop. On further debugging I found out that the while loop in this function is executing for 10 iterations only ie if the "idx <=10". Within this 10 iterations it prints the vendor id and device id of the PCI devices present on the system. For the 11th iteration it gets the chip information 1002,4752 and it try to get the next PCI dev information using the function pciFindNext () were exactly it hangs. Following is the XFree86.log with debug messages before it actually hangs:

Why is that XFree86 not able complete the system PCI scanning? Can you throw some light on the reason for this failure. Is there anyhting specific I am missing.
Also one thing I noticed that all the PCI devices listed by XFree86 are not shown when I issue prtconf command. Why is this behaviour happening?
Is there any faster method to build and test XFree86 source. Because each time after performing any changes in the source I do "make" followed by "make install" which actually takes lot of time.

And also after reboot I confirmed the existence of /dev/fbs/aperture in the system. Then I issued the command to configure XFree86 using "XFree86 -configure" which resulted in a system hang. I power-cycled the system and checked the /var/log/messages, couldn't see any messages. How can I confirm that my aperture driver is working fine ? And I am not getting the reason for system hang when I ran XFree86 -configure. Am I missing any other configuration ?...
