I have an IBM Thinkpad A22m with an Intel Pentium III (Coppermine)
800Mhz.  I custom compiled a 2.4.17 kernel.  I'm also using Sawfish
1.0.1-6.  I have a problem with the mouse input in my XFree86 4.1.0.
Sometimes it doesn't register mouse clicks (requiring me to click
three or four times).  Also, the focus follows mouse seems off.
Most times I have to move the mouse in and out of a window several
times before the focus actually switches.  I originally thought this
was a bug in sawfish, so I asked there.  They said it was actually a
kernel issue.  I'm not sure I really understand that; however, when I
boot the machine with the AC plugged in I never see these symptoms.
If I boot the machine on battery power the symptoms show up right
away.  Also, if I boot on AC but later suspend and then resume on
battery power I don't see any of the symptoms.  Can anyone shed any
light on this?  Is it a known issue?  Is it fixable?

Here are my APM configuration variables for my kernel:

CONFIG_APM=y
# CONFIG_APM_IGNORE_USER_SUSPEND is not set
# CONFIG_APM_DO_ENABLE is not set
CONFIG_APM_CPU_IDLE=y
CONFIG_APM_DISPLAY_BLANK=y
CONFIG_APM_RTC_IS_GMT=y
CONFIG_APM_ALLOW_INTS=y
# CONFIG_APM_REAL_MODE_POWER_OFF is not set
# CONFIG_ACPI is not set
