Are you perhaps using the ts driver for both, or do you use the bm driver for
the vario40 in native mode?

Which values were/are you changing?
Do you use the latest svn code or a stable release tarball?
There have been changes to the TSI driver recently which created problems with

Ultimately, the driver should Do The Right Thing automatically, the user
shouldn't be required to fiddle with individual delay values.  If you have
problems with certain drivers and displays, you should report
those to the list.  If you also found a solution by changing the code,
you should include these changes as a patch in your report.
