11.0beta1a updated on the server. The armv7 initrd file was corrupted, sorry for that. Now it is expected to work, please try. If not, let me know. No other changes made.
I too can confirm the v7.gz boots okay on 3B+.
However now the 11.0beta1a.gz seems to have a problem when booting on Zero W:
On serial console I get:

Mounted the boot partition on another pi, then trying to copy 11.0beta1a.gz I get:
tc@box:~$ cp /mnt/sda1/11.0beta1a.gz /tmp/.
cp: read error: Input/output error
And it fails to copy the complete file:
tc@box:/tmp/remaster$ la /mnt/sda1/11.0beta1a.gz
-rwxrwxrwx 1 tc staff [b]4973924[/b] Dec 11 2019 /mnt/sda1/11.0beta1a.gz
tc@box:/tmp/remaster$ la ../11.0beta1a.gz
-rwxr-xr-x 1 tc staff [b]4931584[/b] Jan 1 00:06 ../11.0beta1a.gz
This is happens with a freshly written image to a formatted SD card. Tried with two different SD cards (brand and size) that are known to be good.
On OSX, when I try to copy the 11.0beta1a.gz file it errors: "The finder can't complete the operation because some data in "11.0beta1a.gz" can't be read or written (error code -36)"
Writing the previous 11.0beta1a image (with the corrupted v7.gz) to the same SD card I can boot the Zero W again.
