If I don't use grub, first I have to figure out how to convert the following grub2 entry into an iPXE menu item:

It's something of a hack, but you can probably work around this by using wimboot. This will expose a virtual FAT-formatted disk constructed from the files previously downloaded by iPXE. GRUB will be able to load the files from this virtual FAT filesystem.

Your boot chain would then be:

• iPXE downloads wimboot plus the relevant Solaris files via HTTP (or whatever other download mechanism you want to use)
• iPXE exposes an EFI_SIMPLE_FILE_SYSTEM_PROTOCOL containing a virtual filesystem containing the downloaded files, and executes wimboot
• wimboot exposes an EFI_BLOCK_IO_PROTOCOL containing a virtual FAT-formatted disk containing the files exposed by iPXE, and executes GRUB
• GRUB loads the files from what it believes to be a FAT-formatted disk
