mga(4) dual-head setup broken after update

[Jukka Salmi <j+nbsd%2009.salmi.ch@localhost>]

Hello,

updating a NetBSD/i386 5.0_STABLE system with native Xorg (X server
1.4.2 -> 1.6.3, mga driver 1.4.8 -> 1.4.11) broke the dual-head setup
I'm using with my Matrox G450 video card:

$ startx
[...]
(WW) MGA(0): Direct rendering disabled
(==) RandR enabled
(EE) MGA(1): Unable to map BAR 0.  Invalid argument (22)

Fatal server error:
AddScreen/ScreenInit failed for driver 1
[...]

(The full [1]log is available, as is the [2]log from before the update.)

Any hints about how to fix this?  Single-head works fine, BTW.


TIA, Jukka
