ok was routing about looking inside the freebsd nvidia source code and was interested to find the following

// ***** Apple variations
#if defined(macintosh) || defined(__APPLE__)
# define NV_MACINTOSH
# if defined(__MACH__)
# define NV_MACINTOSH_OSX
# else
# define NV_MACINTOSH_OS9
# endif
# if defined(__LP64__)
# define NV_MACINTOSH_64
# endif
#endif // defined(macintosh)

now this is just a section in the identifier for cpus and os's and appears to support onboard video according to docs.

Gonna dig some more see if i can find info for someone with some talent lol

Author Updates & Technical Revisions

Follow-up dispatches by @LawlessPPC

Author Update #1 @LawlessPPC 2009-02-25

it would appear that all osx drivers need iokit which from what ive read is quite an undertaking in itself and bsd doesnt make use of this

Author Update #2 @LawlessPPC 2009-02-25

can anyone confirm that the nvidia 9300/9400 has no memory of its own and only accesses system memory

Author Update #3 @LawlessPPC 2009-02-25

yeah looks like your pulling up the same sources as me also max mem 256mb and memory speeds are quoted as ddr3 1333 so looks like it is. Need to try and tap into that driver looks like the only nvidia shared memory driver and very little difference between this and the 8200/8300

Field Note #1 @Taisto 2009-02-25

In specifications they only tell the core speed and "Max supported memory" so i think it uses only system memory. Checked it on few sites, the same everywhere. Still dont know if it could be called a confirmation
