Mount: mounting /dev/sda1 on /media/ntfs failed: No such a file or directory

The bad news: You cannot transfer the modules from the old hostmode kernel to kernel-power because of symbol differences.
If you try compiling them against kernel-power-headers you will be able to get cdrom.ko and sg.ko to load but not sr_mod.ko, which means that it's as good as nothing.

Only solutions to that problem:
1. Revert back to the original hostmode kernel (and lose all the other unrelated improvements that kernel-power features).
2. Recompile kernel-power and add support for necessary modules (such as CD-ROM). I've written a very thorough guide on how to do that.
3. Since I've already done method 2, I now have a kernel image based on kernel-power 46 with support for CD-ROM drives and DVB dongles. I may upload it and post a download link once I've tested it and am more-or-less confident there are no problems or regressions. If you want it earlier, please send me a PM.

Guy,

a) I'm using the kernel-power 46-wl1 that has the bleeding-edge WLAN driver for packet injections. It's important remember the source code is shared;

b) I live in Brazil and the digital tv standard here is ISDB not DVB.

There would be some way to add this drive in a kernel-power 46-wl1?

thanks

About TV/DVB/ISDB - I have to admit that I've yet to succeed in watching TV through the N900. The driver loads but still doesn't really work with the DVB dongle that I have and there's also the issue of userspace software which may have to be patched and/or recompiled from source. Anyway, the whole watching TV issue is still in its infancy and should not be considered as working by anyone. Adding the kernel drivers for DVB is just a first step in the right direction, therefore I think that your concern is a bit premature. CD/DVD drive / CD writing support is confirmed working, though.
On the second hand, you do have a point here - ISDB support is very new in Linux and AFAIK preliminary support was added to the Linux kernel in version 2.6.32 - which is newer than the version used by N900 (2.6.28). If we want this to happen, we may have to upgrade the N900 to a newer kernel - which is a big project.


Would really like to see that happening. I'm gonna send cheve my custom kernel for testing today and if he reports no problems I'll send you the binary (no need for sources as the only changes are configuration).
