2.6.20-10 contains "beta" quality HPA support for libata. Please give it a test by booting it, and look for "Host Protected Area detected."
If you're feeling brave, boot with "libata.ignore_hpa=1" to disable the host protected area (which should enable your whole disk). Please attach dmesg whether it was successful or not. Thanks!
