First the bad news: the network driver in the new kernel is not performing very well, if i remember correctly, this is about twice slower than the original kernel. The maximum speed is around 2.75 mb/s for FTP , 1.4-1.50 mb/s for SAMBA, and 618 kb/s for SSHFS. I have tried implementing NAPI (I will upload the patch soon), but it doesn’t help very much. I have tried to optimize the kernel settings, but no luck so far.
Now, the good news: I have been able to install Debian Etch for ARM in my Agestar using the instruction in here: http://wiki.dns323.info/howto:install_debian. Of course there are differences in booting, and configuring stuff, but the steps to produce the root file system are the same. I have also managed to write new kernel to the flash (by using dd if=bootpImage of=/dev/mtdblock1), so now my agestar will go directly to Debian when i turned it on.
I will clean up the code, and write the instruction on how to install Debian this weekend.
