Hard drive encryption question for dual-boot XP and Fedora

[Kerry Miller]

My company is requiring us to encrypt the hard drive on all laptops. 
We've already got some encryption software but it only works with Windows,
not anything set up to dual boot or anything running VMware.  Do any of
you guys know of some kind of encryption software (open source or not)
that can handle a dual boot laptop with Windows XP on one partition and
Fedora on the other?  He's already told me I need to get rid of my Linux
partition but I need it for network diagnostics, I'm hoping if I can find
an alternative he'll let me and the other network guy use a different
encryption package.

Thanks,
