Comment 4 for bug 669569

Hi Ruslans, thank you for this hint.
This stops the hang indeed, unfortunately it gives other compile errors on 11.04:

ubuntu@ubuntu-WIM-2030:~/Downloads/acerhk-0.5.35$ make
make -C /lib/modules/`uname -r`/build SUBDIRS=/home/ubuntu/Downloads/acerhk-0.5.35 modules
make[1]: Entering directory `/usr/src/linux-headers-2.6.38-8-generic'
scripts/Makefile.build:49: *** CFLAGS was changed in "/home/ubuntu/Downloads/acerhk-0.5.35/Makefile". Fix it to use EXTRA_CFLAGS. Stop.
make[1]: *** [_module_/home/ubuntu/Downloads/acerhk-0.5.35] Error 2
make[1]: Leaving directory `/usr/src/linux-headers-2.6.38-8-generic'
make: *** [acerhk.ko] Error 2

I guess devs would have to fix that too in the repos, but there seems to be no maintainer.
