Yes, it's supported by both debian-installer and GRUB. However, you must use a separate /boot partition or make sure that the root partition isn't too big as GRUB uses blocklists on systems with Sun partition tables. >> -> Question 2: What is the best size for /boot (/dev/sda1)?

Only Grub files or also the kernel stuff? > AFAIR I used around 100-200MB years ago, but this was with SILO. Since the kernel package installs into /boot, the partition should be at least 150-250 MB. I'm surprised that the installer would make it so small as partman-auto has a minimum size for /boot configured. Adrian -- .''`.
