Question about ati mobility X700

Hello muts and all the new community here.I want to make a question. Until now i used bt4 pre final and now i installed the final version of Bt4. My laptop got Ati mobility radeon x700 and i want to tell you that i got many tries to install the ati drivers with apt-get but i got many errors and usually it returns to me broken packages. I even try to install the 9.3 catalyst driver to previous kernel on Pre final version but i got the same: only errors. So i hope you can give me some help or even if someone know if my card is not compatible with that new kernel?

Thanks in advance!


Actually today i installed envyNg and it finds my recommended drivers for my Ati but when i'am tryiing to istall it returns me Error: EnvyNg has detected that the headers for your kernel are missing and cannot be installed.

Any idea anyone?
