	What's the value of dmmax?  Did you rebuild the kernel
	after making the change in the configuration file?  Did
	you reboot using the new kernel?  What limits does limit
	show?

	Changing dmmax should be enough if you used a legal
	value.

	Yes, it is possible to get values that large.  You should
	be able to use dmmin = 32 and dmmax = 8192.  Now the real
	question is whether you have enough page/swap space to back 
	that much virtual memory?  Using a couple of RD54 just for
	page/swap will get you enough if you're using DEC disks.
	3rd party stuff would make it easier.
