load-theme and changing fonts

[Mark Skilbeck <m@iammark.us>]

Hi, all.

In my .emacs, I am configuring the default font with the following
code: 

  (add-to-list 'default-frame-alist
    '(font . "-unknown-Droid Sans Mono-normal-normal-normal-*-11-*-*-*-m-0-iso10646-1"))

Now, if the fancy arrives and I change the theme with M-x load-theme,
for some themes the font will be changed also! This is a pain in the
rear as I must then determine (from my .emacs) the rather offensive
string included in the above excerpt.

Can the theme system be configured to leave the font alone?

Danke!
