This is a bit misleading information.

Short answer is that if Mark believes that his monitor is capable of
sRGB gamut and displays colours as they are characterised by sRGB ICC
profile, he can use sRGB profile as the monitor profile in various
applications.

However, I would doubt that the monitor is of so high quality and he
would probably get more reliable colours by setting the sRGB settings in
the monitor (quasi calibrating it) and create a custom profile with
Huey, Eye One etc. (characterise it).

The ICC profile can do a bit of calibration, too - it is done via VCGT
tag, which adjusts the video card settings. To use the VCGT, one needs a
VCGT loader - like dispwin tool from argyllcms.
