Sergey reported that some much older Dell systems don't support
the OEM string "Dell System" but instead supported www.dell.com
in OEM strings.
Match both of these to indicate that this driver is running on
a Dell system.

Hrm, rather than introduce another variable that we don't use and always perform
both tests, when most of the time we only need to do the first, how about
something like:

Sergey reported that some much older Dell systems don't support
the OEM string "Dell System" but instead supported www.dell.com
in OEM strings.
Match both of these to indicate that this driver is running on
a Dell system.
