you have to ask? hint: ati still don't support x3xxx cards in linux
Well not realy, but ATI claim that they have turned over a new leaf for graphics cards (They are actively supporting an open drivers project), so I wondered what their chipset support was like these days.

In any case, I would hope that in any hardware review of a new chipset or graphics card, the state of Linux support for it would be at least mentioned, and commented on. This chipset is clearly aimed at HPC and low cost applications, which are two areas where Linux is more likey to be used than on more high end systems. If I decide to build up a media Centre box, it won't be running windows my specialist Linux solutions like MythTV are available.

i have 7 frequencies here (core2duo t7400) from 2.17ghz down to 1ghz
Is that a mobile CPU?

In any case, I think 1GHz is still to high, IMHO, the mimimum for any modern clock modifiable CPU, is changing the multipler from 1 up to the maximum the hardware supports, so for example on my Q6600, that should be from 400MHz (the FSB speed) up to the maximum of 2400MHz. A computer that is idling with no one using it does not have much work to do, so it should clock down to a low minimum to save power and heat.

Also, you may not be aware, but the CPU scaling drivers on windows laptops often report more clock frequences than the hardware supports. The extra frequencies come from the CPU spending some of it's time in a kind of sleep states, but these states don't save as much power as a true lower frequency clock, because the CPU voltage is not lowered to match.
