I'm kind of stuck here. I reconfigured and recompiled sigma0 with
--with-s0-linkbase=0x40000, as suggested in the hurd-l4 README. I also
updated my menu.lst to read

  title Hurd-L4
  kernel /boot/laden -D -o vga
  module /boot/ia32-kernel
  module /boot/sigma0
  module /boot/wortel -D
  module /boot/physmem
  
  title Ping-pong
  kernel /boot/kickstart
  module /boot/ia32-kernel
  module /boot/sigma0
  module /boot/pingpong

The first entry gives me some output about memory regions (not sure if
that's laden or wortel or both, I have to check), then crashes:

  00011780733i[CPU  ] MOV_RdCd: read of CR4
  00011780735i[CPU  ] MOV_CdRd: ignoring write to CR4 of 0x00000010
  00011780735i[CPU  ] MOV_CdRd: (CR4) write of 0x00000010 not supported!
  00011780736i[CPU  ] MOV_RdCd: read of CR4
  00011780738i[CPU  ] MOV_CdRd: ignoring write to CR4 of 0x00000080

  00011780742p[CPU  ] >>PANIC<< exception(): 3rd exception with no resolution

However, the second menu entry doesn't work either, I get

  KickStart 0.1
  ...
   roottask   => 0x00300eb0
     (0x001e4000,0x00004474)->0x00300000
  Ooops! No BIOS memory map.

so perhaps there's something broken with my bochs/pistachio setup?
Is anybody using pistachio-0.3, or should I downgrade to 0.2?
