rotating rasterfiles?

[Simon Cox]

I have some rasterfiles (imagery, sort of) which I am importing.
Unfortunately, some of these are rotated 90o.  Can I rotate
these, within grass, prior to rectification, or should I
let i.rectify handle it?  WIll it choke?

I cannot use m.rot90 as the files are already imported as grass raster layers.

SUggestions?
