Yes, you can use something like this in your XHTML code:
<link href="default-rmsdk.css" rel="stylesheet" type="text/css" />
<link href="optimized-webkit.css" media="all and (min-width: 240px)" rel="stylesheet" type="text/css" />
The second stylesheet will be ignored by RMSDK, and can be used to refine your formatting in iBooks and other webkit based apps.
But it's not "querying specifically". It relies in the fact that RMSDK doesn't support media queries.
