Hmm...I'm not seeing any measurable difference in -CURRENT in either the cached or the uncached case. The sequential read-ahead heuristic in the kernel seems to negate any benefit of using a larger buffer size, and using a larger buffer just causes problems when people try to split out larger files (e.g., multi-GB files for transfer to removable media). Interesting idea, though...
