Sorry, can't resist that quip here... Many of the well known x86-based OS', OS-installers and even bootloaders from this millenium trusted the partition tables c/h/s values to match the bios... causing havoc say with PATA drives atached to SATA connectors.
If that weren't the case I guess Linux could have get rid of c/h/s a looong time ago. Hmmm... maybe its time?
