 That's what I'm using.  The "old drm" drivers are UMS.  As this particular
 machine has a Rage 128 card, the correct driver is "r128drm* at drm?".
 It works fine with native Xorg on netbsd-7.  It used to work fine on
 7.99.x before the Xorg r128 driver was up-de-graded.  It then worked fine
 with modular/pkgsrc Xorg until PAX MPROTECT was enabled by default.

 There are no DRMKMS drivers for the ATI Rage 128 cards.  Only radeons,
 and then only if they are new enough (most of mine are not).  Of those
 are are new enough, they are AGP cards and have "issues"...

 Modular/pkgsrc Xorg worked fine before PAX MPROTECT was turned on.
 The MesaLib problem appears to be fixed in pkgsrc-HEAD.
 
 "native" Xorg was broken on Rage 128 and intel i810e devices for a while,
 but works now (still broken for i810e w/GCC 4.8.x).
 
 So I no-longer have a need for modular Xorg on anything except i810e
 machines running netbsd-7.
 
 Thought I'd do something constructive instead of just 'rm -rf' all of
 my -8 and -current modular/pkgsrc Xorg setups.
 
 Perhaps I'll try -current with modular Xorg on the i810e systems as they
 have no DRM drivers at all to confuse the issue.
