Ok, I downloaded HPIOS00_1.0.0.6 from the DeviceVM website. Apparently
it's based on 2.6.20.11. There's a few patches there that may influence
things, but I'm too inexperienced to tell whether they would make a
difference. There may also be something in the kernel configuration
file. The following 2 patches seem to be the most promising?
