Rawhide already has kernel 5.5:

pif# uname -a
Linux pif.optonline.net 5.5.0-0.rc6.git2.1.fc32.aarch64 #1 SMP Wed Jan 15 20:23:38 UTC 2020 aarch64 aarch64 aarch64 GNU/Linux

I have very close to the full 4 GB of ram available.  According to dmesg, 256K of ram is not available - it might be assigned to the video core:

Memory: 3833660K/4096000K available (12924K kernel code, 5450K rwdata, 6272K rodata, 6272K init, 26849K bss, 229572K reserved, 32768K cma-reserved)

Thx for checking Steve. That is pretty good news. afaik rawhide is now the only aarch64 distro on rpi64 (although that might change quickly now with 5.5).
