I am sure others will point this out, too, but to avoid confusion . . .

Yes, except see below . . .

No!  This is not supported with the hp98721 (accelerated SRX) driver.

It does.  On page 4-21, "Use of Starbase Graphics Accelerators":

X11 window; it can, however, be used to accelerate raw mode graphics in the
image planes with the X11 server in overlay mode.
