the changes:
where made to make the installation process goes easy for noobs

but for the other problems you are having
the -f install problem has got a problem with a corrupted package
it is normal to raise the heat while overloaking
and contacts takes 5 seconds to open on the first start up of the boot
reopen it and it will be fast
as well as for photos
so your problems have got nothing to do with the patch

try to fix them
or reflash

and please people if your N900 fell on the ground don't say the patch made it fell
i can see that everyone having problems (even tiny problems)
are posting it in here
the patch made my N900 a lot faster and smoother
we just need to wait for karam to solve the battery tweaks issues
