The config item is already declared in rust/hw/timer/Kconfig, so it's 
enough to do

diff --git b/rust/hw/timer/Kconfig a/rust/hw/timer/Kconfig
index afd98033503..42e421317a5 100644
--- b/rust/hw/timer/Kconfig
+++ a/rust/hw/timer/Kconfig
@@ -1,2 +1,3 @@
 config X_HPET_RUST
     bool
+    default y if PC && HAVE_RUST

I applied it with your commit message.
