PROBLEM: Radeon card displays incorrectly under the 2.6.11 version unless compiled with SMP support

[Lobiuc Andrei]

1.Radeon card displays incorrectly under the 2.6.11
version unless compiled with SMP support.
2.After compiling and installing the 2.6.11 kernel
version, my ASUS Radeon 9200SE 128 MB graphic card
does not display correctly in plain VGA mode. The same
card has no problem with the 2.6.10 kernel.
Regarding radeonfb, dmesg reports:

"
Immediatly after the  GrUB boot prompt, several lines
of text scroll quickly down the screen, then the
display flickers for one second and when the text
comes back it looks huge, at a resolution that appears
to be 320x200 (if not lower). Also, it passes the
boundaries of the screen in all the directions.
In console mode (Ctrl-Alt-F1) the text becomes blurred
and with each line displayed, coloured pixels appear
randomly on the screen.
I tried several "vga=" modes but none seems to work.
I uselessly recompiled several times the kernel with
various graphic configurations.
I made sure that support for framebuffer devices (FB),
ATI Radeon display support (FB_RADEON and
FB_RADEON_OLD), framebuffer console support
(FRAMEBUFFER_CONSOLE), video mode selection support
(VIDEO_SELECT) are all compiled as built-in. 
Drivers for no other cards were built, except for the
first time when vga16fb and vesafb were built, making
yet no difference.
On the other hand, KDE looks fine at 1024x768@85Hz,
except for the OpenGL screensavers which crawls.

Accidentally, one of the compilings has been done with
SMP support enabled on my single-processor machine and
it turned out with this install of the kernel that the
graphic card works ok in such conditions, displaying
the text as it should.
