I figured it out. And here it is, for you folks and for the archives.
I looked through /usr/src/usr.sbin/moused/moused.c and
/usr/include/machine/machine.h and found that provisions had been made
to handle the Alps PS/2 Glidepoint's tap, which doesn't show up as a
button click but as a 'sync'. Unfortunately, in order for those
provisions to be used:
1) moused must be run at a higher driver level. I used 2. The driver
levels are only documented in the source code, however.
2) moused must recognize the mouse model as "Glidepoint". My touchpad
was recognized as "generic", as are most ps/2 mice, I believe. There was
no way to specify the mouse model on the moused command line, as the
command line lets you specify type, not model, and ps/2 connector mice
must always be set to a type of ps/2.
I made a one-line fix to moused.c so that it would recognize my mouse
model as a Glidepoint. The patch is below.

I'm guessing that the ioctl call couldn't figure out my mouse model.
It's not a very elegant fix, but my taps now register as clicks, so it's
good enough for me!
