NetBSD 6.99.19 amd64
>Description:
Using NetBSD 6.99.19 amd64 on an Intel-processor machine with a Sapphire Radeon 
HD 4550 graphics card,
X11_TYPE=modular
set in /etc/mk.conf
upgrading to the latest pkgsrc results in an inability to start the X-server 
with problems similar to those described in:

http://www.freebsd.org/cgi/query-pr.cgi?pr=169875

It would appear at least part of the patch described in

https://bugs.freedesktop.org/show_bug.cgi?id=63583

has been incorporated into a different file for sysutils/libpciaccess 0.13.1.

An additional question is what is the goal of this set of upgrades to xorg?  
Many of the operating systems using pkgsrc including NetBSD 6.99.19 do not 
appear to support KMS kernel modesetting for even older common cards such as 
the Radeon 4xxx series.  Is the expectation that these systems should all run 
the xorg xf86 vesa driver?
