right, and this is also true if you run console DOSEMU and lie to it that you use a CGA graphics card, ie. $_video = "cga", and remove that 640k check in the parser. Caveat emptor -- your video BIOS might NOT like this, weird things my happen, and I haven't tried it. as for xdosemu: it uses vgaemu and I don't think that can be switched off easily. vgaemu pretty much assumes that it can r/w protect all pages from 0xa000:0 up to 0xc000:0. Now if you run dosemu in terminal mode you could go up to 736k (b800), and if you run dosemu in "dumb" mode, well, f000 is even possible, ie., 960k, if you disable EMS too.
