Krzysztof, thank you for your efforts. I've been using PowerMac platform with built-in ATI mach64 and Xorg server 1.1.1.
I will try to reproduce the problem with Xorg 1.1.1 and your options. I do not have the PowerMac and the ATI mach64 card.
In my opinion, Xfbdev assumes that the cursor will disappear when turning on graphics mode with ioctl(LinuxConsoleFd, KDSETMODE, KD_GRAPHICS). It's obvious that fbcon is not doing anything to switch the cursor off when it receives this ioctl, fbcon_is_inactive() prevents it. The problem comes from that something has made it appear, i.e. text mode frame buffer console. I have text consoles on VTs 1 to 6 and X on 7.
One maybe unusual property of atyfb is that the frame buffer is higher than the screen. To make Xfbdev work correctly I needed the patch below.
The patch is not a correct fix. A simple workaround is to set a vyres = yres and disable panning. I am able to reproduce this problem. A cause is that Xfbdev prints some messages after it set up graphics mode, so the screen got scrolled. I do not know what is an expected behaviour (maybe with KD_GRAPHICS no messages should be printed).
