Thanks for the suggestion dreamfire. Increasing the Frame Buffer Size in bios to 256MB increased the reported memory on my card to 512MB also.
The result is I can now work in unity! (Yay!)
Though the problem still exists if I open too many windows, though this is much more manageable now as the tolerance is almost doubled before the bug kicks in. For me this is a suitable work around until the bug is fixed. The system and graphics rendering appears to be a bit more sluggish, though I have no way to quantify this. Will try to reduce some visual effects to increase performance.
