I haven't tried it, but adding the command "uppermem 2000000" before the "kernel" boot command in grub should work. In grub, use 'e' to edit the boot entry, 'O' to open a new line before the "kernel" line, and 'e' once again to insert the uppermem 2000000 command. 'b' boots the modified entry. If all goes well, it should use 1GB for the swap zvol, 1GB for the dump zvol, and you have 2GB free for the Solaris software on the zfs root. Btw. if you use the interactive text (desktop session) installer, you can try to open a terminal window and enable zfs compression (standard compression lzjb, not gzip !) on rpool/ROOT/* while it creates the swap and dump zvols. That way I installed almost all of SXCE on an 8GB usb flash memory stick, using ~ 4.5 GB of the available spce (including 2 GB for swap and dump). The only problem is that the installer does not know about zfs compression, so you have to install one of the smaller install clusters, and manually add missing packages later on.
