Having owned my M505 (M505B2) model a few weeks, I decided to put it through the ATITool GPU overclocking/test utility that came with the Omega drivers. The GPU and video memory of the Mobility Radeon 9600 in this notebook was originally clocked at modest 320/210 MHz, but as the test went on I could hardly believe my eyes as the numbers were getting higher and higher... until reaching 429 MHz for core and 248 MHz for memory, artifact-free! 
As you might know, the Mobility 9600 and 9700 are identical chips that differ only in the manufacturing process, which allows the 9700 to run cooler and reach higher clock speeds. Well, the 9600 in my M505 can go 5% faster than MR9700's regular clock speed of 400 MHz!
.
Playing it a little safer, at 420/240 MHz, my 1.5 GHz Banias lappy scored 10920 in 3DMark 2001 without any tricks aside from disabling vsync, nothing even to keep the Pentium-M CPU lowering its speed when idling.
Understandably, the cooling fan had to work harder, but in short...
