Hi,

I read in an old thread that this question was asked once and you replied
you never heard of this chip. Maybe now the situation has changed? If not,
please take a look here:

http://www.jmicron.com/product/jmb360.htm

It claims the chip is ahci compatible, but the libata ahci driver can't
detect it (tried 2.6.14.2 and 2.6.15-rc7).

Maybe just adding some ids or such is enough for supporting it?
Following lspci -vvv -xxx regrading the Jmicron stuff:

Well, I tried adding the ids into ahci.c, but this wasn't enough:
