(the problem's the same with the default 5.4 kernel from the ISO, and with 5.3)
>Description:
When Xorg is run on my laptop, the screen goes dark for a long time. Sometimes, initialization succeeds and I have the classical pattern on the screen - but then, the server is very unstable and prone to segfaults ; sometimes it just freezes or segfaults. Switching consoles also takes a long time (~ 10s) with the screen going dark.
Strangely, the server output, even in verbose mode, doesn't show any error message.
I don't have this problem with XFree86.
>How-To-Repeat:
Install and run Xorg from FreeBSD 5.3 or 5.4 ISOs on a machine with a 82845GV integrated video chipset.

 Does the problem continue if you try xorg-server-snap as a replacement
 for xorg-server?  If it does, I'll see if I see anything relevant
 post-6.8.99.16 to merge.

 No, it doesn't ! xorg-server-snap fixed it :)

State-Changed-Why:  
I couldn't easily identify the commit responsible for fixing this, and the 
i810 driver has undergone enough change between 6.8 and HEAD that I think 
just saying "use xorg-server-snap if you experience this" until the next 
stable release is reasonable.  Hopefully we'll get xorg modular working and 
then we'll be able to sanely update drivers on a regular basis.
