Well, I built a 2.6.22 kernel last night, and in tests this morning there's no difference relative to the ALSA behavior seen in 2.6.25-rc4. Since the question came up (or was strongly implied), I took the time to check the status of IRQ 5 in /proc/interrupts, and while it shows up as assigned to the sound card, no interrupts are being seen/processed by the es18xx driver. When I remove the snd-es18xx module and install the snd-sb8 module with the same parameters (other than there's no second DMA channel), the /proc/interrupts counter for IRQ 5 increments as expected when playing sound files.
At this point I'm pretty sure the es18xx issue isn't a regression: it's "just" a bug that has been around since I first loaded 2.6.X on my Alpha.
