Q6600 not recognised as Intel!

[imacken]

My Q6600 is not being recognised as such. Shows up correctly in 'About this Mac' (after OSX Tools correctly identified it) but there is no 'Processor Name' in System Profiler. It also shows up correctly in 'grep cpu' info.
This is stopping me installing certain apps that need an Intel CPU.
I've tried various SMBIOS settings from doing searches, but nothing I try seems to work.
Any ideas?
