It now tolerates window dragging on this unaccelerated moderately high
resolution VGA without any sound dropouts. There are still dropouts while
scrolling in Mozilla, so it acts much like 2.5.73+Con's patch, as expected.
I had 2.5.74 freeze up a couple of times yesterday, resulting in a totally
dead, unpingable system, so now I'm running 2.5.74-mm1 with kgdb and hoping
to catch one of those beasts in the wild. The most recent incident occurred
while switching from X to text console, which did not complete, leaving me
with no debugging data whatsover. That was with sound running. Switching to
the text console always results in a massive sound skip, so there is a clue.
XFree is running generic VGA, so I don't seriously suspect the driver, and
even so, it should not be able to kill the system completely dead.
System details are as I reported earlier:
AMD K7 1666 (actual) MHz, 512 MB, VIA VTxxx chipset. Video hardware is
S3 ProSavage K4M266, unaccelerated VGA mode, 1280x1024x16. Software is
2.5.73+Gnome+Metacity+ALSA+Zinf. Running UP, no preempt.

Daniel
