That's a very reasonable idea in the current situation. The problem is 
that the xorg-server ebuild will begin building more and more X servers 
based on various combinations of USE flags. For example, kdrive will be 
part of xorg-server 1.1. Xgl will likely be part of xorg-server 1.2. 
Already we've got Xdmx, Xnest, Xorg and Xvfb.

Clearly one may desire to install only a certain set of these servers. 
Right now, my working copy has it set up so that USE=minimal in 
combination with USE=(dmx|kdrive|xgl|other group of servers) causes the 
Xorg server to not get built. But expressing that in RDEPEND gets quite 
complex.

Perhaps the "minimal" flag is the wrong way to go, and instead I should 
add a "xorg" flag that defaults on to build the Xorg server. That 
approach would allow for a reasonably simple expression of the driver 
PDEPENDs inside like this: "xorg? ( driver list )".

A valid problem with this approach. Is requiring everyone to unmerge 
drivers a worse solution than breaking some people who emerged drivers 
directly?
