"Cannot allocate memory" when run vmware-workstation binary for Linux

[Zoong PHAM <zoong@zoong.com>]

When trying to power on a virtual machine
I get this message "Cannot allocate memory".
And in /var/log/message there is a message
"Jan  1 22:19:30 garlic /bsd: vmmon: Vmx86_ReleaseVM: unlocked pages: 0, unlocked dirty pages: 0"

I installed the binary vmware-workstation-3.2.1-2242 for
Linux and enable running Linux binaries in /etc/sysctl.conf.
Basically I followed the instruction at:
http://www.monkey.org/~marius/pages/?page=VMWare_for_OpenBSD

I use OpenBSD-3.6 with all the patches, 512MB RAM.
According to vmstat and top, I still have about 350MB RAM free.
In vmware, I set the virtual machine to run various OS as the guess
OS with 128MB RAM (vmware's minimum recommendation).
I tried with lower and higher setting for the guess OS RAM above
without any luck.
And I also tried with ulimit and login.conf to set most
of the settings related to memory to "infinity" but the problem still exists.

Here is the output of ulimit -a
# ulimit -a
time(cpu-seconds)    unlimited
file(blocks)         unlimited
coredump(blocks)     unlimited
data(kbytes)         1048576
stack(kbytes)        32768
lockedmem(kbytes)    454544
memory(kbytes)       454544
nofiles(descriptors) 1024
processes            532

Any help would be very appreciated.

Thanks,
