32-bit Chip RAM detection

I'm trying to detect WinUAE 32-bit Chip RAM from EmuTOS. As I understand, it doesn't use AUTOCONFIG.
What is the proper way to detect 32-bit Chip RAM? Start at $10000000 until there is no more RAM?...

Would it be OK to enable the instruction cache at startup, disable it before memory test, and re-enable it afterwards?
