Well, it's still in beta.  Obviously, MySQL would like it to be GA, so there are outstanding bugs that are preventing it from getting there.  MERGE tables are an alternative in 4.1 or 5.0, although those also have a number of issues that can cause problems if you aren't careful.

As I understand, MERGE wokrs only with MyISAM, we need some solution for InnoDB. Do you know of anything that can help us split very large table (handreds of millions of rows)  into several ones?

Outside of partitioning, no.  You can, of course, do application-level partitioning (say, A-D in tableA, E-J in tableE, etc.) - but that can be quite a change at the application layer.

I'd take a real good look at all of the open bugs (at http://bugs.mysql.com) related to partitioning before deciding to implement 5.1 in it's current beta state for this feature.
