. . . my wife's computer, "Isis", . . .

. . .
I also note that Linux (on Isis) gave me this boot-time warning message:

* The chipset may have PM-Timer Bug. Due to workarounds for a bug,
* this clock source is slow. If you are sure your timer does not have
* this bug, please use "acpi_pm_good" to disable the workaround

I downloaded the pmtmr_test.c program by OGAWA Hirofumi

to test for this, compiled with gcc (gcc -opmtmr_test pmtmr_test.c),
ran it, concluded that Isis did not have this bug, and
added acpi_pm_good to the kernel command in /boot/grub/menu.lst
. This made Linux noticably faster on Isis.
