Fails inside Promox VM

I am guessing this is a new issue either with `chwd` or with newer updates to Proxmox itself. I have installed CachyOS in the past with no issue, but this was `2024-12-05`. Trying to a new install using the same VM setup, no virtual video GPU, only passthrough of an Intel Arc A380. Machine type is `q35` and using `OVMF (UEFI)` instead of `SeaBIOS` for BIOS.

Install always fails with failing to run chwd:
```
thread 'main' (2815) panicked at src/data.rs:356:14:
Failed to read board name: Os { code: 2, kind: NotFound, message: "No such file or directory" }
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
```
Install log: https://paste.cachyos.org/p/cd7a2a9.log

Bypassing the run of chwd during install will give the same error once I am rebooted and loaded into the OS proper. This also happens on my old install VM as well.

Start by reproducing the installation and post-reboot failure in the described Proxmox VM configuration, using the linked install log and the chwd panic at src/data.rs:356. Run with RUST_BACKTRACE=1 and inspect how the board name is read when no virtual video GPU is present. Done means chwd handles this VM setup without panicking and the installation completes.
