Pointsec and other partition encryption sw

[Anssi Porttikivi]

Does anyone have any idea why f.ex. my company standard Windows/NTFS
encryption by Pointsec does not work with GRUB?

Currently Pointsec reseller says there is no way to boot from anything
except Windows untouched MBR, I don't know how to set up
Linux-Windows-multiboot with that, if it is ever possible.

I don't see any reason why Pointsec needs to be called from Windows
MBR, and if it needs, why GRUB could not fake that to Pointsec. Maybe
somebody has an indea how to patch GRUB to do that?
