FreeBSD does not have KMS.. 
On another notebook Radeon XPRESS 200M 5955 
it works ok...

As I said in the bug report, the chip works very good Only after power
on,
and the driver "ati" or "radeon" is not aware of KMS either...

Seems to me that the screen memory is not align propper with
the registers on the chipset, a propper align situation  occurs only
after power on,
or after about 10 resets.. 

A propper reset or initial program in the chip (using the ati, or radeon
driver)
would resolve the problem...

Can someone please point me to a documentation of the radeon 6250 that
explains how to reset the chip to power on state???

Thanks for any help,

Sergio
