Just for the record, I got this solved and it had nothing to do with 
kernel update :)

At some point, I started to use USB mouse without a reboot and all 
worked well. Then when I upgraded the kernel and rebooted (couple weeks 
later) both the USB-controller and the Nebula card got same IRQ! And 
since then the card didn't work and I thought that it was related to the 
kernel upgrade.

'cat /proc/interrupts' and 'lspci -v' among others are your friends when 
solving IRQ problems.
