puh :-)
Quite a lot of version for such a small patch ;-)

no :-(

I thought that it could be done with a single ike this
highway=* & mkgmap:synthesised=yes & bicycle=yes [0x04 road_class=2 road_speed=3 resolution 24]

but we probably also want different road classes for the cycleways 
depending on the highway=* tag value.

Maybe we can code a solution in the <finalize> section?
Something like
highway=* & mkgmap:synthesised=yes & mkgmap:bicycle=yes { set mkgmap:resolution-min = 24 }

That would work similar to the mkgmap:road-class-min=* tag.

The problem with this is that the original idea was that an  "Element type definition" 
(the stuff in the square brakets) is a constant, and the code required to allow
tags like mkgmap:road-class-min=* is very error-prone.
