[PlanetCCRMA] kernel-rt(PAE) questions

Does using the PAE kernel version on a 1GB memory machine cause a noticeable decrease in peformance?

In particular, when scrolling down through a webpage that has a lot of banners and such with Firefox, I notice a lag that is getting to be painful.

So I removed the PAE kernels and went to the standard kernel in Fedora 11, with the result that somewhere along the line I broke Jack and can't get jackd to come up properly.  (Don't worry about this problem, I'll probably do a reinstall of Fedora 11, install the non-PAE kernel, and leave the PAE kernels on the system.)

Just curious,

Hmmm, I think I will have to rethink the dependencies for
planetccrma-clore, sorry for the problem. You could of course rpm -e
planetccrma-core in the meantime, that will not remove the already
installed packages, and they should upgrade fine with a yum upgrade. 

What is it that did not work when trying out the rtPAE version?

You should just ignore them, I think (unless you have a card that uses
one of those drivers, of course).
