Hi Luca, et al,
Yes, I can reproduce without the tainting kernel module (fglrx.o). Debugging a bit, the corruption shows up when using ATI's "fglr" device driver in XF86Config. If I switch to using the unaccelerated "Radeon" driver provided by XFree, then the screen remains readable upon return from X. Thus, the kernel module is OK, the ATI proprietary glx and dri modules are OK, it's just the driver.
However, I still think this belongs as a kernel issue, because it appears to be a failing of the radeonfb.o module to properly set the radeon registers. Remember that version 0.1.4 of the driver does not have this issue; it works just fine with the ATI fglr X driver.
