[2.1.6?] /proc/pci weirdness

Hello friends,

Please forgive me if I'm an idiot, but I'm wondering about the IO
values listed in /proc/pci. When I boot my system and log in, my video
card shows this:

Bus 0, device 17, function 0:
VGA compatible controller: S3 Inc. Trio32/Trio64 (rev 0).
Medium devsel. IRQ 9.
Non-prefetchable 32 bit memory at 0xe0000000 [0xe0000000].

Once I've started X, it looks like this (note the IO address):

Bus 0, device 17, function 0:
VGA compatible controller: S3 Inc. Trio32/Trio64 (rev 0).
Medium devsel. IRQ 9.
Non-prefetchable 32 bit memory at 0xf8000000 [0xe0000000].

The above output remains forever, whether I'm in X or not. Once I start
it, it switches to this and never goes back.

I looked at the source to try to figure out what the values represent, but
I could only minimally make sense of them.

If someone would be so kind as to enlighten me so that I might understnad
what process is occuring, I would be most grateful.

cheers,
-bp
