Do you think I should start another thread just to change the display resolution and control the fan speed even though they all relate to managing video playback on this card?

Warning, I have never done either, never had need to. But did some poking around:

How to add resolutions to an X server (any reference to MDM, LightDM, etc... you have to replace with gdm3 if necessary): http://community.linuxmint.com/tutorial/view/877

For changing display resolution via KMS: http://nouveau.freedesktop.org/wiki/KernelModeSetting

And yes, a new topic about controlling the fans would likely be a good idea as it would have a more specific title and get more notice. Maybe better to post it in the Hardware forum.

For the time being I will continue to persue the resolution question in this thread. The discussion for fan speed control is now here.

Update: I reviewed the links you gave me and it states that KMS is enabled by default on AMD/ATI cards after R300 but when I run
cat /proc/fb
to confirm this, it returns radeondrmfb. This seems unexpectedly terse, is it normal?

I decided to try and make a modeline to test as per the instructions in the link above:

I ran xrandr and it returned
Screen 0: minimum 320 x 200, current 1024 x 768, maximum 8192 x 8192
DIN disconnected (normal left inverted right x axis y axis)
DVI-0 disconnected (normal left inverted right x axis y axis)
DVI-1 connected 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
1024x768 60.0*
800x600 60.3 56.2
848x480 60.0
640x480 59.9
1280x1024_60 (0x15e) 109.0MHz
h: width 1280 start 1368 end 1496 total 1712 skew 0 clock 63.7KHz
v: height 1024 start 1027 end 1034 total 1063 clock 59.9Hz

so the next step cvt 1280 1024 verifies the mode and returns
# 1280x1024 59.89 Hz (CVT 1.31M4) hsync: 63.67 kHz; pclk: 109.00 MHz
Modeline "1280x1024_60.00" 109.00 1280 1368 1496 1712 1024 1027 1034 1063 -hsync +vsync

then I added the mode and ran xrandr --newmode "1280x1024_60" 109.00 1280 1368 1496 1712 1024 1027 1034 1063 -hsync +vsync
which returned
X Error of failed request: BadName (named color or font does not exist)
Major opcode of failed request: 150 (RANDR)
Minor opcode of failed request: 16 (RRCreateMode)
Serial number of failed request: 27
Current serial number in output stream: 27

Any clues as to what is happening here?
