Agreed!
I set it in my kernel config, which is basically a copy from
/src/sys/arch/amiga/conf/GENERIC.
However even with CV_AGGRESSIVE_TIMING, I get an pixelclock too high
error with modes 12 and 13. These modi work fine with AmigaOS. Do I
have to live with these errors? It's a pity because mode 12 is the ony
I would like to work with.
Here my /etc/grfmodes:

Without CV_AGGRESSIVE_TIMING, I get errors with modes 10, 11, 12, 13
and 16.
