I tried 2.6.16 on my laptop with the latest fglrx drivers. After
enabling AGP and a strange MTD device to clear all the undefined
symbols, I got the driver to run. Unfortunately, when I go to a
website that has flash, firefox hangs immediately.

I then tried the driver from the kernel, turning on the DRI for
radeon, and got the same thing, only it took a minute.

I suspect there may be problems in the AGP subsystem in 2.6.16. On my
myth box I run an NVIDIA, which has its own built-in AGP, and 2.6.16
is just fine.

Did you try an earlier fglrx? I know that 8.19.10-1 has it's own AGP
drivers built in. Or maybe wait for 2.6.16.1?
