Playing with the kernel parameters didn't help either. I had to boot into Mandriva for a couple days for work, but I got back on Pardis today and brainstormed.
Turns out, the problem was in the xorg.conf file. It wasn't complete; that's all it was.
I actually copied my xorg.conf file generated for me in Mandriva over the one generated by Pardis. Worked like a charm; the driver is the DRI Radeon driver (ATI), I have 3D, and I have my full WXGA+ screen.. it's even ready for me to plug in my other monitor

The xorg files are pretty standard, I think as long as I don't have to change the video settings in the Pardus Display Settings applet it will be ok. Even then, I know what to look for now.
Only thing I may have to do is tell xrandr how I want my Xinerama set up when I get both monitors connected, but that's a cinch.
This was an old troubleshooting gimmick I used to use, I don't know why I didn't think of it before. But, for anyone with this laptop (HP/Compaq 6910p), try replacing the contents of your xorg.conf file with the following... back yours up first, of course.
CONTENTS (I removed remarks by Mandriva):
Section "ServerFlags"
Option "DontZap" "False" # disable <Ctrl><Alt><BS> (server abort)
AllowMouseOpenFail # allows the server to start up even if the mouse does not work
#DontZoom # disable <Ctrl><Alt><KP_+>/<KP_-> (resolution switching)

That's it

Thanks everyone for replying it really was a great learning experience. I REALLY like this distro and have already moved from OpenSuSE 11.2 KDE-4.3.4 on my main machine, and am converting everything over from Mandriva to Pardus on this, my work laptop.
Cheers!
