Thanks for your reply. At the moment, i'm still booting the built-in 
Fedora 8 Kernel:

2.6.23.1-49.fc8

For now, at least i have sound with a not so clean workaround - routing
all apps that use alsa to the jack-plugin and connect streaming output 7 
+ 12
to physical out 1 and 2. Which lets me only use 2 of 8 physical outputs,
a little annoying for a soundcard in this price class ;)

Under Fedora 7 i was using alsa 1.0.14, F8 uses 1.0.15. Maybe there's
something wrong concerning the hdsp card in this release.
