I am an ongoing VMWare customer (Workstation 6.5.1 currently) so I am
more than familiar with the any-any patches.  I do not do realtime work
inside a guest but I do use the same kernel for audio and vmware.  The
latest workstation build did not require an any-any patch so I am pretty
happy there.

I have been running Linux on Laptops for nearly 10 years.  I let go of
suspend a long time ago.  With -rt patches, video binary blobs,
ndiswrapper, etc. I just don't bother.

I just got the new laptop Friday, so we shall see how this goes as there
should not be the need for binary blobs (chipset, wifi, video are all
Intel and thus all upstream).

I have a custom 2.6.28, the one difference I see is that I have HZ=1000.
