my 2cents: I spent a lot of time with MicroCore Linux. It runs very well, and probably would run Dosemu. BUT the problemis that it is not a *real* Linux ditro in the sense that is does not install to a harddisk, it rather boots every time as if it was from a cdrom. There are a few tricks to include what you have bade into next boot, but it is complex and not automatable... So I abandoned it...
As for using memory, there is no problem using more than 66Mb of ram in Dosemu, it provides good memory drivers.
