You could use a data URI, not that that's very pretty in this particular  
case though, since you'd have to encode the "whole" svg file (only the  
root and the gradient are necessary, but it needs to be a valid svg image).

E.g fill="url(data:image/svg+xml;base64,...encoded full svg...#mygradient)"

Here's a testcase:

Anyway, this illustrates why it would be nice to add the CSS gradient  
syntax to the SVGPaint syntax (read: fill, stroke etc).
