I'll be trying that just a little later today, as in, sometime in the
next half hour or so.

I don't have either of the two files mentioned above.  As far as the alsa
userland, I would think it's all "reasonably" current.  I'm running Debian
"Etch" fully patched/updated.  I'll normally refrain from running things
in the "unstable" or "experimental" categories unless something is broken
in the "stable" tree that isn't getting fixed (e.g., a libc problem).
Beyond that, I also tend to run the latest kernels to make sure we (the
community) get an early warning if there are problems with kernel
updates/changes on the Alpha architecture.  Because it's a reasonably
small list, here is the relevant "dpkg -l" output for alsa packages:

Reported on the results of the various "sox" tests in that article last
night.

For all of the above, I need to mention I am/was running an unpatched
2.6.25-rc7 kernel.  "cat /proc/interrupts" shows absolutely no interrupt
activity for the ES1888.  Here's the current and complete output for an
uptime of 1 day, 14:14:

Ok.  Let me boot on the kernel with the "miata_no_mmap" patch and give
that a spin.  I'll report back shortly.
