On my stationary machine it finds all hard-drives, partitions, oses and every single Linux kernel. You'll just have to edit /etc/default/grub for your needs on the Linux from where you updated grub i.e. for getting rid of splash and recovery mode, setting defaults etc.. I also have an ice1712 card, a hoontech dsp24, and it worked ootb in 10.04 64bit. But just in the moment I have problems with sound/alsa in kernels 2.6.32.23 and 24 generic and preempt. With rt kernel 2.6.33.26-rt and jack2 (available i.e. in falktx ppas) and alsa updated to 1.0.23 all audio is fine. Even if both your cards are selectable in PA I think your problem has to do with multiple sound-card setup which seems to be not trivial in Ubuntu. Can you select them in Qjackctl too? good luck Gerhard
