I had a similar problem with shared memory.

I found an option in /sys/conf/NOTES.

I think it could help in your case, if u increase 
% options  MAXDSIZ=(1024UL*1024*1024)
% options  MAXSSIZ=(128UL*1024*1024)
% options  DFLDSIZ=(1024UL*1024*1024)
apropriately.

E. g. in your /sys/<arch>/conf/<kernel name>
options MAXDSIZ=(2000UL*1024*1024)

But I dont know, if that is a good idea... Maybe you should use
nextboot(8) in case your box does not like the new kernel... :-)
