I can't really speak to how much love it gets now vs then, but I do
know that quite a few arm cross-development frameworks use it for
testing/simulation work. You can write emulators for a lot of the
custom hardware on an embedded board or SoC into the Qemu binary and
then be able to boot an image with most of the same functionality on
either Qemu or the real board.  This is a great time-saver!  I think
the Android SDK device emulator is based on Qemu's ARM emulation as
well, and that's even more widely used.  So, I think it's fair to say
that at least the ARM emulation gets a fair bit of love these days.
