Now that I traced the codepaths of compat_ioctl, I see that this particular problem has been worked around by calling do_screeninfo_to_user() which resided in fs/compat_ioctl.c (as of 2.6.14) and now moved to drivers/video/fbmem.c where it actually belongs. The problem in my case was my incorrect implementation of compat_ioctl method in my driver that called filp->f_op->ioctl() for that matter. Stupid me.
