Others have mentioned here that lshw is not to be trusted, at least
where video cards are concerned. I've not tried it - YMMV.

01:00.0 VGA compatible controller: ATI Technologies Inc Rage Mobility \
M3 AGP 2x (rev 02) (prog-if 00 [VGA])
Subsystem: Dell Computer Corporation: Unknown device 00b0
Flags: stepping, 66Mhz, medium devsel, IRQ 11
Memory at f8000000 (32-bit, prefetchable) [size=64M]
I/O ports at ec00 [size=256]
Memory at fdffc000 (32-bit, non-prefetchable) [size=16K]
Expansion ROM at <unassigned> [disabled] [size=128K]
Capabilities: [50] AGP version 2.0
Capabilities: [5c] Power Management version 2
--------- snip -----------------------------
Note the Memory; I happen to know it has 8Mb shared with main memory.
I believe the "AGP 2x" means it's not capable of doing dri under X (or
at least not without a proprietary driver from ATI, if such a beast
exists).

Sounds to me like you mean "GHz", not "MHz". 1.33 GHz =~ 1330 MHz.
