Xiangchuan,
I think it would be worth the effort to install ATI's proprietary Linux x86_64 driver, found by following the links here:
http://ati.amd.com/support/driver.html
It takes a bit of effort (it requires compiling a kernel driver), but I have done this once on a system (but not FC6) and it was pretty easy and took no more the 20 minutes. This will ensure that you have a 64bit driver for your 64bit FC6.

Hi Nick and Kevin,
I installed the centos4_x86_64_v4.0.1 on my laptop. The tkmedit could show volume and surface data, the tksurfer could not display surface brain. Then, I changed it to centos4_v4.0.1. In this version, both tkmedit and tksurfer did their jobs. So, the same issue as v4.0 exists on my laptop. In addition, I am not able to enter number in all the boxes with numbers in both tkmedit and tksurfer. Because I have an ATI x1600 video card in the laptop, is it possible that the insufficient linux support for this card caused this issue?
Thanks,
Xiangchuan
