I had this IRQ problem and tried to see if this would be solved with 2.6. The problem was still present with 2.6 and alpha, but it is solved by letting ACPI handle the interrupts. Only, then the slowdown comes over. I see non-stop load at 99.9%, never resting. I reach an useable status (let's say, being able to playback a DVD with MPlayer with acceptable performance) by re-nicing the offending process. As of default it runs at -10; if I set it to 1 (just higher than normal processes) I manage to do things. I wonder if it is possible to find out where these events that clog the process come from.
