All things setable by systune are described in files under:

/var/sysgen/mtune so if you look in the gfx file under there you see:

*
* tunables for graphics
*
* gfxlockablemem: max % physical memory that may be locked by graphics
*
gfx: static

* name default minimum maximum
gfxlockablemem 20 0 100
gfxlockablemem_gt64 50 0 100

There were some rare cases with Impact gfx where this was exceeded and gfx
crashed with 'OUT OF MEMORY' type errors but they are fixed now I think and
tuning that parameter isn't needed anymore. I don't think I've seen anyone else
have to tune it on other systems. I would say that unless you really think you
have a problem with gfx running out fo locked memory then it's best to leave it
as set, tweaking it doesn't effect performance providing all is running OK.

Cheers
Rob
