What error do you get? If you use qjackctl for starting jack make sure 
that the "Interface" field is pointing to, say, "hw:1". "Frames/Period" 
to the default of 1024, and "Periods/Buffer" to the default of 2. Try 
starting jack...

What does it print in the "Messages Pane"?

My laptop has fc13 installed and while I don't have a 1010 I don't see 
problems starting jack with pulse running. We have tons of Delta 66's at 
CCRMA that work fine as well. Usually 1010's are easy.

Let's see what problems you are getting.

You need to install the akmod-nvidia package (part of the Planet CCRMA 
"testing" repository on fc13" - install the planetccrma-repo-testing 
package to enable it). This is what I have in the /boot/grub/grub.conf 
line for the kernel in my laptop (with the nvidia driver):

   nouveau.modeset=0 rdblacklist=nouveau vmalloc=512M
