alan,

thanks for your work on the linux kernel.  i've been using the 2.4.21-ac
patches for some time on a sharp actius av18 laptop with great success.
in particular, i'm pleased with the acpi implementation.  

i tested the redhat severn kernel-2.4.21-20.1.2024.2.1.nptl on this
laptop recently and found the acpi fan features missing.  upon booting
the kernel the fan stopped and the cpu temperature sensor began to
"whistle" on the motherboard.  considering that the upcoming redhat
release will be using acpid instead of apmd for power management, i'm
concerned that other redhat customers may experience the same problem.
please forward my concern to the appropriate developers at redhat and
request that they consider your acpi patch as a possible solution. for
reference, i've attached dmesg output from the kernel-2.4.21 with your
patches applied.

will.
