Thanks - using older versions helped.

Using fixup4.dat and start4.elf from this zip file works, with one caveat: if the usb receiver for my keyboard and mouse (Rapoo E9100P) is
in a usb port when the boot starts, the boot (at least some of the console output) goes extremely slowly and eventually fails.
If I insert it after the kernel has booted (after the login prompt shows up) the usb keyboard and mouse works normally.
usbconfig output:
root at generic:~ # usbconfig

ugen0.2: <vendor 0x2109 USB2.0 Hub> at usbus0, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=SAVE (100mA)
