The BIOS update has been around forever from Compal (the people who actually
OEM the unit for Dell), you can get their generic BIOS at
http://software.tuxtops.com. This probably violates your Dell warranty but I
know many who use it and we've now installed it on all the 5000e systems we
own, without any problem.

I'm not sure why Dell is taking so long to get an update to it consumers,
but it probably has something to do with the fact that Linux isn't a
supported platform on this machine. Their official stance appears to be
"APM isn't supported on this laptop, only ACPI." That's pretty bogus since
everything but this one system call works, and even that works with the
Compal generic BIOS, so I'd more likely guess it's just not high on the
priority list because it's not important enough for their largest user base
which is of course Windows.

Later,
Tom
