This is true.  According to one person I spoke with at HP, he said
that SRX box would never support the accelerated graphics in X.  He
did say that the TSRX (turbo-SRX) does support the fast hardware.


Part of the explanation was that X works best with a simple, dumb
frame-buffer, and that having the graphics pipeline in the path
complicated the situation considerably.  What I don't understand
is why the SRX can't be used with X, but the TSRX can be.  What's
so different about the SRX that it just doesn't work?

Oh well.  It's still great stuff.
