SHORT ANSWER:
Haiku's Intel video driver needs updating to work properly on certain
video cards ( 945G chipset, found in Atom netbooks & desktops ).
LONG ANSWER:
Haiku's Intel video driver is based off X Org driver.
The issue is caused by p2 range. X driver updated p2 from 10 and 5
to 14 and 7 range but Haiku's has not been updated ( still uses old values ).
http://dev.haiku-os.org/browser/haiku/trunk/src/add-ons/accelerants/intel_extreme/mode.cpp?rev=29174#L214
I think I changed out those values but did not work for me. It must need
more than just changing out the p2 values.
You will notice on my ticket the attached jpeg. You can see that my p2
is out of range on first try and then system tries to compensate by using
values that fit in the defined PLL max & min range but fails ( freezes ).
I believe same is going on for you.
You will have to make due with VESA until Intel video driver is updated.
