I submitted a pull request for the 64bit constructor earlier today.

Actually the asm code didn't need changes. The 2 issues where
- which register to use for what data.  Compile an fpc example with -al 
and see what fpc uses. Then luckily all necessary changes existed in the 
32 bit include, so I could copy it with minor changes.
- a wrong typecast of a 64 bit address to 32 bit.

I didnt know when this was changed in fpc, so the fix now breaks it for 
older fpc  < 3.0
