Thanks for the reply, Andrew. I was beginning to think that I'd committed an 
LKML sin :-)

Yes, it is about the same. On 2.6.25.4 (and earlier), the icons appear within a 
second or two, but with 2.6.26-rc2 or later, it takes about 20 seconds. I've 
now built and installed -rc5 and am seeing the same behaviour.

I've also built -rc5 on my laptop. On that my kernel uses the older IDE drivers 
rather than libata. The boot proceeds with no pause, but I do see the same 
delay in the desktop icons appearing when I attach a usb-storage device.
