Hi Eric,

Please try the revised patch.
This patch should be applied against OpenChrome Version 0.5 RC6 I just
The older patch I obsoleted should not be used since it contains a "death trap"
bug in the patch that freezes the system if VT1632A is detected.
The so called 'death trap" bug is an issue of the compiler / make generating
the code when pointer types aren't compatible (this should be flagged as an
error, but it doesn't), and this is why when you tested the patch, it was
I found the error in the code today (sometime Thursday afternoon), but due to
equipment problems at my place (i.e., the computer I commit the code to the
repository was having problems) and other family commitments, I was not able to
upload the patch until right now.
The computer is working fine now, so I am able to upload the revised patch.
Also, please test this patch only with Wyse Cx0 and not Vx0 at this point.
Wyse Vx0 will need an additional patch to manipulate DVP0 (Digital Video Port
0) register so that DVP0 source is IGA2 (display controller 2), not IGA1 Vx0
seems to  set DVP0 source to.
I will upload the patch to get DVI working with Vx0 over at Bug 94259 after you
confirm that this particular bug (Bug 96673) is fixed and closed.
This fix will go into Version 0.5 RC7, hopefully by tomorrow (Friday).
