Hello,
After looking for Buslogic VMWare docs I found the following:
There were often rumors that ESX server is based on Linux GPL code. I
think I've found a prove for it from an official VMWare/EMC document (just
save the PDF document for reference):
http://www.vmware.com/pdf/esx_15_manual.pdf
p.269:
ESX Server's Mylex (Buslogic) driver is based on the Linux BusLogic
version 2.1.15 driver.
p.270:
The ESX Server uses two different drivers to support the device family,
one based on the Linux ncr53c8xx version 3.4.3b driver and the other on
the sym53c8xx version 1.7.3 driver.
More clearly stated that ESX SERVER is based on Linux driver GPL code and
therefore ESX Server is derived work of Linux GPL v2 code and therefore
the WHOLE ESX SERVER has to be put under GPL v2 (even when run as userland
program of a Linux kernel, because the ESX source/driver depends on the
Linux kernel and Linux GPL code is linked).
This is at least valid for VMWare ESX server 1.5.
Any comments? Any plans?
Ciao,
Gerhard Wiesinger

Historically, the drivers you mentioned have had close ties to the
corresponding FreeBSD drivers and were dual-licensed. So it is
possible that Vmware obtained a non-GPL version of those drivers.

The mentioned version ncr53c8xx-3.4.3b is from Sat May 12 12:00 2001. From
sources one can see that e.g. Alan Cox, Ronald van Cuijlenborg (and some
others) made already GPL v2 changes in V1.10 and V1.9 from 1998 and 1997.
Therefore derived work is from GPL v2 code.
