I have an old Toshiba Tecra 8100 w/P3-600 and CentOS 5.2 32 bit, so
there will be extreme variances, but....

I had trouble with this, too.  I have a DLink USB wireless plugin,
which may be part of the problem, but I wound up using ndiswrapper and
the Window$ driver, and that seems to work as long as I can remember
the right sequence of commands to execute to ensure that it is up and
running.  (Need to script that....)

You might want to post some info on what kind of sound processor is in
your machine.  I can't help you here - my sound works fine.

Have you gone to system->preferences->screen resolution and set that
as well?  I could not get any widescreen modes to work with my (home)
desktop system and a new 22"WS monitor until I did that.  Then they
all worked.

Also, check your xorg.conf file to make sure all the possible modes
are there - sometimes you have to edit in the Modes line with all the
resolutions your monitor can handle.

Whole different animal - different kernel and everything else down the
line.  Probably not going to help much.
