Try a Mustek scanner for example. HP scanners are much better behaved
than most of the el-cheapo scanners. E.g., with my Mustek scanner,
increasing scan buffer size by a factor of 4 will decrease color scan
times by a factor of four (scan time is dominated by the number of
backtracks the scanner has to do due to a full scan buffer).

But I agree it's bad taste to ship pre-compiled binaries assuming a
128KB kernel buffer. The real problem is that the Linux kernel
doesn't allow to determine what the limit is. I'll see whether we
could have that fixed for Linux 2.2.
