(2.4) ext3 - commit=NNN overridden by laptopmode (bdflush)

When looking into the ext3 commit code I saw that it has a commit=NNN mount option for specifying the log update time (same as in 2.6). The problem is that this value is overridden by the laptopmode code that was added which uses the value of get_buffer_flushtime which takes its value from bdflush, which makes that option obsolete.
It looks to me that the bdflush code should be taken back out of the ext3 code.
I don't mind doing it but only if there is interest.
