mtdblk, apm, and wondering if you received my email?

Hi Klaus (and debian-handheld!), I'd sent you an email on Oct 21st
but didn't receive a reply so I'm wondering if it actually made it out.
On the pocketworkstation site Klaus mentioned he'd like some mtdblk modules so
you have could jffs2 on a cf/sd/mmc card. I compiled those modules (for the OZ
kernel) and have successfully loaded them, however the filesystem takes sooooooo
long to mount if it's not ro (even on my laptop) that it's near useless.
Maybe somebody else will have better luck. The modules are here:
http://undertow.2y.net/zaurus/bin/mtd-modules-z5500-2.4.18.tar.gz
Instead of that, I just compiled an ext3 to help avoid the long fsck delays
on my 1GB SD card. That module is also on my site: http://undertow.2y.net/zaurus/
Regarding APM and screen brightness controls, I'd like to hack fbvnc to replace the
volume control with a brightness control, however I don't know how to control the
brightness without using zapmd, which seems to cause problems with Opie.
Using either cru or just "ssh localhost cmd" (with a properly configured authorized_keys file)
I could send cmds to apm, but don't know what they should be and googling so far
hasn't turned up anything promising.
..worst case, I supposed I can just grab the source for the opie brightness control and look
there, but I would think a simple interface via /proc would be available...
Some other things I thought I'd mention that make Debian on the Z much more enjoyable and give you MUCH
greater flexibility is using either a complete remote root disk and/or remote swap space. This allows
you to have as much swap as you need for building large programs, or for running more apps concurrently.
The biggest win is remote root though-- you can have yourself a 3GB remote NFS mounted root filesystem, and
use that as for example as a complete development, or for testing apps on your Z without actually touching
your local filesystems, or even to run PocketWorkstation on a Z WITHOUT an SD card with additional space.
I'd been planning on putting up a web page on how to do it, and when I do it'll be at the above site,
but in short you just mount a remote filesystem via NFS/SMB, create either a swapfile or filesystem in a
file, then just do:
losetup /dev/loop0 /mnt/z/SWAPFILE
swapon /dev/loop0
..for remote swap, and similar for remote root.
Anyway, have to run, if anybody is interested in further details, pls let me know.
