A regular PC doesn't need special multi-touch drivers.
I know that Ubuntu 9.10 worked great on an old tablet PC I put it on, so 10.10 might work without a hitch on your multi-touch capable device. Then again, it might not.
EDIT: It seems as though multi-touch may have been in Linux for some time now. Commenter lkm32
in the article Zaine linked says:
... multitouch has been available in Linux from at least 2007 (yes even before windows) and synaptics touchpad multi-touch from even before that. It was integrated into the kernel before Windows 7 was ever released and always had much more extensibility.
I know the title could be misleading but if you actually read the article you would find that Canonical (company behind Ubuntu) was simply making a new multitouch software interface (as in new way to make the user experience better) and to set standards.
