Having trouble installing a piece of hardware? Want to know if that peripheral is compatible with Linux?

ATI Radeon 32mb PCI & acceleration

Hi all,
don't know anything about this subject and have a few questions to ask. If some one can give me some advise it would be very much appreciated.
I have just installed a Radeon 32mb graphics card, PCI format, I have no AGP, on my old pc. It appears to work fine but am a bit puzzled as to how or if hardware acceleration is enabled or supported with this card. Am I right in thinking that the hardware acceleration is 'supplied' by the agpgart module. If this is so will this AGP module work with my PCI card or do I need something else. Dmesg gives these errors...
agpgart: no supported devices found
drm: initialised Radeon 1.7.0 20020828 on minor 0
drm: radeon_unlock *ERROR* Process 964 using kernel context 0

Also I read a lot about people going off to ATI to download drivers, is this necessary under XFree 4.3.0?

What command, or how do I check the status of hardware acceleration?
Glxgears gives output of 18,600FPS, 13,500FPS and 13,300FPS. Is this about right for this configuration?
I am running Mandrake 9.1, XFree86 4.3.0, have an AMD K6-2 running at 500mhz and 128mb RAM.

Thanks in advance, BashTin.

Those speeds from glxgears make it sound like you have accleration enabled, but I'm not sure how.

There are drivers in XFree for your card, but they do not support 3D acceleration, which is why people download ATI's binary drivers. I would be surprised if the ATI drivers supported your card. However, if it's an old pc without AGP, why are you looking for hardware acceleration?

Thanks for the reply Bluephile.
First as I mentioned I know very little on this subject. But as I understand it hardware acceleration is where rendering (or some sort of video processing) is done by hardware, in this case the chip on the card as opposed to software and/or the cpu. Yes/no? If this is the case wouldn't it be best for me to use hardware acceleration on my relatively low spec pc to relieve it of some of the work load and speed up/improve graphics output? Or am I missing something in the detail?
