compiled in the kernel I don't have this problem.
I don't know if I've already told you but there is a fix which is
always the same and is:

In researching this I've come across a lot of mention of flickering
issues with various Radeon 9x00 chipsets, on Windows as well as Linux.
The symptoms seem to suggest that the framebuffer sets a register

I haven't had yet any bug confirmation. But I think that sooner or
later it will represent because even if the splash is no more present,
the module vesafb is loaded. and the bug is visible when this module
