Yes, I've been experiencing this problem for long time.

The only thing I can say that it's related to the TFTP emulation that QEMU
is doing. If you load the modules from a virtual hard drive, it's booting
much faster.

It would be great to solve this issue by either submitting a patch to QEMU
or changing the boot media on GRUB.
