Guess it depends on what Pi.
ArmV6 nope no Chromium, ArmV7 yeap and boy its seems fast compared to Raspbian.
Pretty sure after netctl enable wlan0-YourWiFi-NAME and an update my next step was pacman-S chromium
Setup your GPU mem
echo '
gpu_mem=128
dispmanx_offline=1
dtoverlay=vc4-fkms-v3d
dtparam=audio=on
'>>/boot/config.txt
sed -i 's/rootwait/rootwait cma=128MB/' /boot/boot.txt
echo '# avoid sleep
xset s off -dpms
# browse a generic page
chromium --fullscreen
https://https://archlinuxarm.org'>.xinitrc
chown alarm:alarm .xinitrc
echo '
# startx on login
[[ -z $DISPLAY && $XDG_VTNR -eq 1 ]] && exec startx > /dev/null 2>&1'>>.bashrc
chown alarm:alarm .bashrc
I think that will pull in everything without even need for fbturbo or mali.
As for v6 generally apart from raspian it seems a no.
