I've also been able to repro this on a much older desktop machine which has an ATI radeon card attached over AGP. However, on this machine I had to re-run "strace gdmsetup" around 15 times before it froze the machine. I think it's a kernel issue.
When the machine was hung I attached gdb to strace and saw this stack: #0 0xb7f9c430 in __kernel_vsyscall () #1 0xb7ef2e83 in write () from /lib/tls/i686/cmov/libc.so.6 #2 0xb7e89cdc in _IO_file_write () from /lib/tls/i686/cmov/libc.so.6 #3 0xb7e8ae57 in _IO_do_write () from /lib/tls/i686/cmov/libc.so.6 #4 0xb7e8a6fa in _IO_file_sync () from /lib/tls/i686/cmov/libc.so.6 #5 0xb7e7e4d9 in fflush () from /lib/tls/i686/cmov/libc.so.6 #6 0x0804d0fd in ??
