On rt3, only USB is slow... Using the trackpoint works nicely.
I noticed that hotplugging my USB mouse was not successful. I had to 
reboot with the mouse attached, to make it work.

I'll try to test the rawhide kernel soon-ish to let you know about this.

I'm also missing the ipw3945 module - I can't recall if the fedora 
kernel pkgs usually provides that module or not, but my dkms based 
version of it fails to build because of the interrupt structure changes, 
and that kinda limits my use of the -rt kernel to reboot-test-reboot-again.

On the positive side, this T60p thinkpad usually makes a high-pitched 
squeaky noise when idle while running on batteries. That annoyance is 
gone with the -rt kernels - Hooray :)
