thanks - I've got it working now. I must say setting up X is a bitch but given the immense range of video and sound kits out there, its probably hard to make it easier.
Its puzzling that XF86Setup seems to disappear if you upgrade to sid but no doubt in due course I'll find out which particular user error causes that problem. Meanwhile its nice to have enlightenment working...I've had to reinstall owing to a wildly over-enthusiastic installtion of 500MB of X stuff that dselkect decided my life would not be complete without. Currently upgrading to sid again. Thanks again to all who sent pointers...
