Some days ago, I reported a Bus Error during configuration of

Now, after two days of debugging, I made it to localize the reason
for this crash:

The bus error is caused in cvattach(), while determining the size
of the RAM on the CV64. I have a 2MB CV64, so that cv_has_4mb()
writes some test patterns to non existent memory - Bus Error!
Maybe Michael Teske and the other Cybervision testers have a CV64
with 4 MB Ram, so they never had problems.

After commenting out the cv_has_4mb() call and hardcoding a 2 MB
RAM size, the configuration of grfcv0 works!
