I have recently tried Mandriva One 2008 and it worked great on my system. It
detected everything properly and even installed the wireless flawlessly. It has
a great control panel and lots of tools. It was fast and great looking. The only
fly in the ointment is its package manager which is RPM based, has fewer
packages available, and it was not as descriptive as I would like. If you are
inclined towards RPM distros (I am not), it is worth a look. PCLOS is a fork of
Mandriva and it uses some of the same applets. However, it uses Synaptic, but it
is still RPM based .

PC OS is an Ubuntu derivative which is based on Xubuntu and it is not so fussy
about using proprietary software and drivers, so multimedia works out of the
box. It also tries to slim things down by using Flock over Firefox and has some
Google stuff installed. It is larger than Ubuntu (fits on a DVD). Unfortunately
its name is to close to PCLOS.
