	I don't use glint driver, only wsfb.

	I know. I have tried some graphic adapters without any success (system 
only panics).

>>> show console
returns 'graphics'.

	Now, my PWS500au runs with 7.99.51. I have quirks on the right of 
screen (I have sent you a photo) and I'm unable to obtain more than 256 
colors.

	I have seen in another mail in this thread :

Also, it's entirely possible to have pm3fb switch to 32bit colour with
ioctl(WSDISPLAYIO_SMODE, WSDISPLAYIO_DUMB) and back to 8bit with
ioctl(WSDISPLAYIO_SMODE, WSDISPLAYIO_EMUL) - a few of my other drivers
do just that so X with wsfb can run in true colour.

but I don't know how use this information...

	Best regards,
