I'm having a similar situation on an Acer Aspire One AO110 netbook. This system has Intel mobile graphics, not ATI - is there another bug filed for non-ATI?

lspci reports my graphics as:

00:02.1 Display controller: Intel Corporation Mobile 945GM/GMS/GME, 943/940GML Express Integrated Graphics Controller (rev 03)

I don't know whether my Lucid install is using an open driver for this, or whether a restricted driver is available. Or maybe it's not the graphics subsystem at all.

The temperature sits at 56 C even when idle in "Powersave" mode. (I confirmed I'm in powersave mode via "cat /sys/devices/system/cpu/cpu0/cpu_freq/scaling_governor" ... the frequency is generally 800MHz not the max 1.6GHz, but even at half speed the temp doesn't drop.) An identical machine running Windows XP stays in the low 40's when idle. I'll be happy to provide more information if desired.
