I have a DEC3000/400, onto which I have 1.5 installed, running XFree 3.3.6, 
as per the instructions at the monash university(?) site. 

I have a PMAG-something or other that is quite capable I believe of 24-bit 
colour, but by default X starts in 8-bit colour. This is a real downer when 
it comes to running apps remotely ('though twm looks fine ;-) ). I know in 
XFree under Linux there's a XF86Config file in /etc, but I could find no 
equivalent under NetBSD.

Also, while I'm at it, can I get X to dual-head? I have two framebuffers in 
this machine, but only one gets activated on boot (dmesg says something like 
"unknown device PMAG-JA at tc0 slot 4 not configured"). I assume that's the 
8-bit device, otherwise I'll have to do something hardware-related to enable 
24-bit colour!

Any help appreciated,
Cheers,
MvdW
