Ah:

cpu% ls /dev | grep realmode
cpu%=20

But:

cpu% ls '#'P
'#P/archctl'
'#P/cputype'
'#P/ioalloc'
'#P/iob'
'#P/iol'
'#P/iow'
'#P/irqalloc'
'#P/realmode'
'#P/realmodemem'
cpu%

cpu% cat /sys/src/9/pc/pccpuf | grep realmode
	realmode
cpu% ls '#'P | grep realmode
'#P/realmode'
'#P/realmodemem'
cpu%

However, there is still:

cpu% ls /dev | grep realmode
cpu%=20

cpu% cat /rc/bin/termrc | grep P | grep -v -e '^#'
for(i in f t m v L P u U '$' =CE=A3 =CE=BA)
cpu% cat /rc/bin/cpurc* | grep P | grep -v -e '^#'
NPROC =3D `{wc -l </dev/sysstat}
site=3DEXAMPLE

So:

cpu% bind -a '#'P /dev
cpu% ls /dev | grep realmode
cpu%=20

Nevertheless, I went ahead and tried:

cpu% aux/vga -m vesa -l 1024x768x32

This time, it crashes the system:

panic: assert failed at 0xf015b72a: hp !=3D nil
