(notice that I've customized a bit my GRUB setup, but that shouldn't matter in the scope of this discussion)
The only line that mentions gfxpayload is:
# vga= is deprecated, grub2 handles this just fine
# making grub2 res == linux fb res
set gfxpayload=keep
Which, through a bit of grepping in /etc/grub.d (and as noted by grub.cfg itself), is generated by:
/etc/grub.d/00_header
line: 182
The VGA line could be inserted because it appears to be more reliable than the gfxpayload option on some systems, and it is compatible with the way the syslinux bootloader (used in the live medium) specifies video modes, but I am not 100% sure of this.
Probably changing the way the installer works could be more clumsy with the gfxpayload option, I imagine a new variable should be added to sabayon-grub with special attention to set it only if it isn't already set (unless the inclusion of the file is moved on top of /etc/default/grub, but it would be equally troublesome), also retrieving its value in live mode reliably could be more painful (since an actual resolution is required rather than a VESA mode), but again, I'm not entirely sure about this.
