thanks for the quick response, Tony's patch fixed
the issue for me, the console fonts are fine again.

after that, the screen goes white for half a second
and becomes black with a large terminal font on it
(the one I get without framebuffer, I think), the
text there is printed undistorted ... shortly after
that, I get a flash, and the mode switches to a much
smaller font (the final framebuffer font) and the
kernel messages written there are already distorted.
half a second later (or less) the penguin appears at
the top area (undistorted), when the bootup is done
I get the following prompt (which again is okay)

	bash-2.05b#

typing anything there is distorted again ...

Hrm... this is a a pristine 2.6.16 without any patch applied? 

yep!

Also, what video chip revision do you have exactly? 
(lspci will tell you)

it did and it should have told you too :)
(it's in the original mail)

pressing enter several times leaves 'copies' of
the caracters on the screen, forming vertical bars
the prompt (bash) is now always fine, the copy one
line above (as all the others) is distorted ...

note, the bootup is not much different with older
kernels, except for the strange distortions ...

attached my kernel configuration, just in case
it is related ...

# CONFIG_VGA_CONSOLE is not set
CONFIG_DUMMY_CONSOLE=y
CONFIG_FRAMEBUFFER_CONSOLE=y
# CONFIG_FRAMEBUFFER_CONSOLE_ROTATION is not set
CONFIG_FONTS=y
# CONFIG_FONT_8x8 is not set
# CONFIG_FONT_8x16 is not set
CONFIG_FONT_6x11=y
CONFIG_FONT_7x14=y
# CONFIG_FONT_PEARL_8x8 is not set
# CONFIG_FONT_ACORN_8x8 is not set
# CONFIG_FONT_MINI_4x6 is not set
# CONFIG_FONT_SUN8x16 is not set
# CONFIG_FONT_SUN12x22 is not set
# CONFIG_FONT_10x18 is not set

Interesting... I suspect there is an endian bug in the new 
font code that hits odd sized fonts (or non-multiple-of-8 
fonts). Can you try enabling 8x8 and 8x16 instead of 6x11 
and 7x14 fonts and tell me if those work ?

yep, 8x16 font works as it seems ...

Tony: If my suspition is confirmed, I think that's your call :)

best,
Herbert

Cheers,
Ben.
