I'm sorry, the Windows machine isn't running virtual. It's a real old noise
making server. He stored it away in another room and uses a silent Linux
machine. Does that change anything? I think it does.

I will assume the Windows machine is virtual and the guest on the Linux
host, whth the later running natively.

He can set a profile with vcgt tag to test that. The xcalib project on
http://xcalib.sf.net has such profiles. I guess neither.

CM is possible on Linux with varying concepts and provided by several
projects. Just ask bing.
When he sets the profile inside the VM in Windows, then Photoshop is
responsible for ICC conversion and any installed CMS on Linux should use
sRGB as its monitor profile. If he uses a colour server on Linux, this one
is responsible for the ICC conversion and the monitor profile in windows
should be sRGB. He must then be careful to not do double colour correction,
as the host and guest CMS'es can do colour calibration and probably ICC
colour correction on their own. An other pitfall could be to try multi
monitor support inside a guest system.

Yes of course are there drivers. It is a computer, even if only virtual.
But typical there is not much support for VCGT, but you can test it easily.
hope this helps,
