Really it's very easy, just try to launch second vmware copy ;-(.
It's easy to fix this, and enable only one vmware session per
host, but I'm looking for better solution.

Oh no, I never tried to use sound. Ok it's added into my TODO list.

I don't have a SCSI CDROM, so I can't to test this. I suppose that vmware use
ioctl to read subchannel, and SCSI cdrom driver complained about it.

I really don't know what is the sense of bridging networking, may
only to use some brain damaged protocols such as NetBEUI. If someone
really needed the bridge networking, probable much more easy to enable
BRIDGE support in kernel, and added support for bridge in the vmnet
driver.

Really this is patch must be addressed to Pierre Beyssac.
If you are interested on more correctly work of .../meminfo I have
just another patch, probably much more correct (probably only one leak
in swap info).
