setpci failing inexplicably

Hi, I just noticed with "lspci -v" that my docked Radeon card has a latency of 0. For every other device (for example my sound card which is at 00:05.0 with 64 latency by default) I can run:

sudo setpci -v -s 00:05.0 latency_timer=ff

to maximize the time before it gives up the bus. The output I see is:

0000:00:05.0 @0d ff

and sure enough "lspci -v" shows that my sound card has 248 latency (ff rounded down) just like it should. When I try this with my radeon card:

sudo setpci -v -s 09:00.0 latency_timer=ff

I again see

0000:09:00.0 @0d ff

but "lspci -v" still shows that its latency is zero. Also note that I see "radeon 0000:09:00.0: setting latency timer to 64" in dmesg.

Has setpci failed for anyone else before? Does anyone know a reason this may happen or a utility that can help me find out? Thanks.
