Thats the problem, not all of the vars are IN stylevars (yet), therefor not changeable without manual editing.

The only way I know how to change ALL style attributes is to:
1) in admincp, options, style and language settings: change "store stylesheets as files" to YES.

Assuming that directory it mentions is writable, it will dump all of the css into files which are located in:
/clientscript/vbulletin_css/style00001l

(look at all of the thousands of style definitions in those files...not ALL of those are accessible via their built in stylevars manager)

Its just easiest to add something like this to additional.css (which will be empty to start):
.foruminfo {min-height:40px !important}
rather than messing with their css files which will get overwritten with upgrades.

change the height to whatever works.

If someone has a simpler explanation I would love to hear it as well.
