Hmmm I've previously run through the entire Debian installer using the
in-built QEMU userspace network stack and have successfully managed to
detect an rtl8029 network card and get a valid DHCP lease? What appears
to be the problem?

Please do. Given that you seem to be able to reproduce this, the most
interesting part would be to try an older kernel (2.6.32 as mentioned
elsewhere in this thread) and/or try building a kernel without
performance counters in order to determine whether this really is the
cause of the lockup even under emulation.
