Trying to get skype working on HP 5450

Been trying to upgrade HP 5450 to PPC2003, it went real smooth, but my wifi stopped working after tha upgrade. Had to install a firmware (ver. 0.100.5.39) update and than a driver update (3.2.4.133), after that wifi worked fine. Well almost, except for some unkwown reason it sometime just disappears, where I have to remove the battery for 5 seconds before it appears again.

Heard on the forums that I can somehow "unlock" the 5450 so that I have 128MB of RAM!!! Don't know how true this is, but sounds a bit bogus. But I am all ears. If anyone of HP 5450 users can help me out, please do.
