I'm not L4 hacker, but recently I've built and ran L4Linux on raw hardware
(586) with dope.
When I saw your message I tried to run the same binaries on VMWare and It
works!
Try to use my GRUB config (don't forget to fix the paths) and L4linux config
file. They are given below.

Here is some of my info:

VMware version: 6.5
Host OS: other 2.6.x Linux

GCC version: 4.1.2

L4Env config: default
build command: make oldconfig O=/path-to-buildu-dir && make
O=/path-to-buildu-dir

Fiasco config: default + 'Handle and preserve segments' option was enabled
CPU type: Intel Pentium / AMD k5
build command:
  cd kernel/fiasco &&  make BUILDDIR=/path-to-buildk-dir
  cd /path-to-buildk-dir && make menuconfig
  make

L4Linux config: x86-native_defconfig + L4 build directory was set to
'/path-to-buildu-dir'
build command:
  cd l4linux-2.6 && make x86-native_defconfig && make menuconfig
  make

GRUB: I used my 0.97 GRUB, the only thing that i did - I overwrote
/boot/stage2 file with the patched one

GRUB config:
 title L4Linux-2.6
 kernel /boot/L4Linux/bootstrap
 modaddr 0x02000000
 module /boot/L4Linux/main -nokdb -serial_esc -comspeed 115200 -comport 1
 module /boot/L4Linux/sigma0
 module /boot/L4Linux/roottask task modname "loader" allow_cli task modname
"bmodfs" attached 5 modules
 module /boot/L4Linux/names
 module /boot/L4Linux/log
 module /boot/L4Linux/dm_phys --isa=0x00800000
 module /boot/L4Linux/simple_ts -t 300
 module /boot/L4Linux/rtc
 module /boot/L4Linux/l4io
 module /boot/L4Linux/l4dope
 module /boot/L4Linux/bmodfs
 module /boot/L4Linux/l4linux26.cfg
 module /boot/L4Linux/libloader.s.so
 module /boot/L4Linux/libld-l4.s.so
 module /boot/L4Linux/vmlinuz
 module /boot/L4Linux/drops.rd
 module /boot/L4Linux/loader --fprov=BMODFS l4linux26.cfg
 vbeset 0x117

l4 config:
 task "vmlinuz" "mem=64M load_ramdisk=1 ramdisk_size=16384 root=/dev/ram
l4env_rd=drops.rd"
   all_sects_writable
   allow_vga
   allow_cli

Hope it will help.
Best regards, Alexander Valitov
