I'm afraid the answer is, for now, no.

PMAG-JA is two-framebuffer-in-a-single slot. It can provide 8 bit pseudo
colour screen and 24 bit true/direct (=no LUT) colour screen simultaneously.
They can be composited in an arbitrary shape with 1 bit "transparency"
bitmap. The original intent was motion video application with audio capability.
PMAG-JA has no hardware 'accelleration' feature inside. It is useful when you
build a new TCWSCONS kernel adding "tfb" configuration lines appropriately.

No. It's an i960 driven SCSI board. There were variations of PCI and
VAX XMI other than TURBOchannel.
