No, it's impossible. Single Xserver capable of multiscreen must
handle whole hardwares.

It's impossible too. PX product line is not designed as dumb
framebuffer. Framebuffer memory can not accessible from CPU; it sits
behind 'graphics processor'; a common design mistake (ahem) of any
hardware accelerated graphics board. Please note also that 3MAX has
smaller TURBOchannel slot address space which can not hold and map a
large framebuffer memory.

Obtaining SFB (PMAGB) or SFBplus (PMAGD) is a way to go. 3D gadgets
are proprietaries by nature, and any open software activity is hard
to exceed the original performace which the designers could achieve.
