Yeah, I tried many more here actually, with Arch I only need APPEND root=...
(no rootfstype, ro, rw, rootdelay, etc.).

(turns out it's not what I thought it was, though I did try root_delay, it is
actually rootdelay...)

Here's my syslinux.cfg with more comments:
PROMPT 1
TIMEOUT 50 # <-- here
DEFAULT gentoo
LABEL gentoo
LINUX ../kernel-genkernel-x86-4.0.5-gentoo
INITRD ../initramfs-genkernel-x86-4.0.5-gentoo
APPEND rootdelay=5 root=UUID="6fc386ff-8342-42a2-be02-51a6eccf8430"
rootfstype=ext4
# ^^--- I added this just now because you said so, though in the
last message I had root_delay
# Neither of those has any effect (conditions 2 and 3 I told you about
remain as they were)
# (as I thought this has nthing to do with the bootloader)
# pen (normalmente /dev/sdb4): UUID="6fc386ff-8342-42a2-be02-51a6eccf8430"

I don't know, I always used an initrd. Though I must say, that is the
phase of starting the PC I understand the worst.

Ah, so that's why it showed with a couple of dashes above it :)
All the best,
