sustained writes to SD (is there a solution?) Options

[raduga]

There have been several threads posted over the past year and a half, from users with various sizes and brands of SD card that for some reason or another, just WONT work with sustained write.

Some suggestions have been offered:

* Patching the kernel to allow async (or FS_SYNC=N) access to SD
* mounting the partition with -o async options
* using "updated" sd drivers (a new mmc_sd.o was posted to ZUG some time ago)
* trying a different brand, different size of SD card
* mounting as a loopback device
* format as fat/ext2

For people with SD write issues, which of these has worked?
In my limited experience, with a new Lexar 256mb SD,
both cacko qt (1.21) and pdaxrom (1.0.5) kernels showed problems
mounting with and without -o async didn't help
the patched mmc_sd.o does not initialize properly, and doesn't load right
both fat and ext2 seem to show similar issues

has anyone found a way (reliably) to get their flaky SD working with sustained writes?

What SD media do you use (brand, size) and have you had any problems so far?

Sorry for the horrible ugly poll [there should be a better way to condense this, or at least allow more poll options]
