X-Mame Linux SVGAlib and Joystick problems

HI there, I am configuring my system to run X-Mame. All is working
well (sound etc working), apart from the following:

1) When I terminate X-Mame with ESC or CTRL-C, the screen is black and
I have to reset the machine to restore it. I have put a wrapper script
around xmame.svgalib that does a savetextmode and textmode (and even a
restorepalette), but it makes no odds. Shouldn't X-Mame restore the
graphics upon terminaton?

2) I don't seem to be able to set the resolution for it to use - is
that done via modeline config in vgalib.config? Not such a problem at
the moment as I am using a CRT, but I will be using a flat panel
monitor soon.

3) I cannot get my USB PS2 joystick to work. Actually this is a Linux
problem as jstest shows that it knows all about the joystick but no
events occur when i press buttons etc. This isn't so much of a problem
as I will soon be using proper arcade controls via an I-PAC
(www.ultimarc.com), and the controls will appear as keycodes via USB.

My system:

Linux 2.6.16.5 on Debian Etch.
SIS 661FX integrated graphics - Linux framebuffer support all working
and SVGALib configured to use chipset SIS. No modelines set, but the
framebuffer device seems to be able to read monitor caps without
problem.
X-Mame 0.104
SVGALib 1.4.3-22

Any help would be most appreciated!

Cheers,
Andy
